Not really. I am planning to use Buildbot for CI but as part of the build
process, I'd like to run some tests as well. I need some flexibility with
regards to accounting of the tests (how many passed, how many failed etc.).
The tests will be disparate. Some will be shell scripts, some might be
python programs. I need a framework to run all of them and report
success/failure.

Srinivas,

While I am not aware of a book, some useful readings are likely to be 
found in the "Data" section at 
http://www.ambysoft.com/onlineWritings.html (I read a lot of his 
articles many years ago, and did find them quite useful then.

This is not necessary for ActivePython [activestate.com/activepython]
which installs a "python26.exe" along with "python.exe".

Why not use nose? You can create a wrapper test that runs your shell 
scripts and nose will execute it.

I thought of that but it sounds like a bit of a hack to run tests that way.
I haven't used nose *that* much. Does it allow some form of extension which
I can use to write custom test types (eg. with different reports etc.)

Nose (after reading the docs a bit) is a unit test framework for python
code.

While I might be able to wring it's hand (nose?) to make it do general test
running, I don't think it was intended for that.

I found something called pandokia http://stsdas.stsci.edu/pandokia/ which
looks like what I want. Anyone have experience with it?

All you need to do is to make sure your $PATH chooses the correct
python. When you compile python, the --prefix=<foo> value gets
compiled in Modules/getpath.c. This is how the python binary knows
where to look for it's correct bits.

Only thing you need to look out for is PYTHONPATH. If you have this
set, make sure it points to the appropriate version of libraries you
are trying to pickup.

Hi all,

In our college, we have a mod_python based web application for our
intranet portal. We have a local testbed where the student devs have
their own logins and they work on their own subversion working copies
and publish their sites using mod_python configuration in
/etc/apache2/sites-available/default and userdir module. But we very
often face a problem like this.

All the users have their own copies of the web application and when
one user opens and navigates through the web application when other
user is doing the same with his copy, on clicking links and all, all
the addresses start getting changed into those of the other user and
not mine. We use Debian Lenny and the versions of apache2 and
mod_python shipped with them with the mpm-prefork module. How to avoid
such an issue.

For example when I click on a link in a site
http://localhost/~user1/blah it gets changed it to
http://localhost/~user2/blah and causes confusions. This issue happens
only when the users publish their own sites and use them concurrently.


Thank you.

Regards,
Guruprasad.

I haven't deployed through mod_python myself but in your situation, wouldn't
it make sense to have a local webserver per developer and only push the
'production' version to the mod_python+ apache combo?

We push only the 'production' version to the live server with
mod_python+apache combo. But we have a local testbed server running
apache with mod_python. We are using the same apache to serve the site
of all the developers' sites hosted in their respective home directories
and we encounter problems I mentioned above in such a scenario.

Of course, having a local webserver per dev will make a lot of sense,
but I thought that in my scenario, I can keep all the development on a
single testbed server and still have multiple devs working on their own
copies of the application. The webserver becomes centralized and working
from any other machine through SSH is easier than setting up a webserver
in every machine where the dev works. This approach may be flawed so I
am open to ideas and suggestions regarding this and also regarding how
to solve the problem.

Guruprasad

I have found a solution to the problem from
http://mailman.modpython.org/pipermail/mod_python/2009-December/026397.html.

The idea is to create a sub-interpreter for every published site by
using 'PythonInterpreter' directive. I can use directives like

<site1>
PythonInterpreter site1
</site1>

<site2>
PythonInterpreter site2
</site2>

where
PythonInterpreter directive has to be given a unique name that could be
anything.

I want to call python from my C program, which will perform same

As Python is better to do with large number, so I called python.
Is there any way to this type of embedding.

Are you sure you need C for your app at all? If you're having things like
dealing with large numbers, maybe it makes sense to do the whole app in
python and dive into C only for parts that need to interface with low level
hardware or require speed.

  Beats me, this one. What can C not do with large numbers which Python
can do ?

This is alpha release,for testing. I don't know if Andrew Kuchling has
updated the whatsnew doc. The best piece of whatsnew for alpha
releases is Misc/NEWS document.

 I quoted the release manager Benjamin Peterson himself. Guess he knows

 Btw, I actually read through the whatsnew link before posting and it
 *is* updated.

Well, I was not nitpicking. It was just for information.  I remember
this discussion somewhere that amk usually updates before the beta or
the actual release and Misc/NEWS is the source for whatsnew.

Is this a GUI construct? I'm sorry if I seem daft but I can't really place
what a notebook is in this context. :)
If it's something you've done yourself, maybe you can have a 'stale' boolean
attribute for the page which you don't want to see.

Maybe it shouldn't get ported back. If 2.x becomes as good as 3.x without
the backward incompatibilities, it's going to hurt adoption. It *is* after
all an improvement and not a critical bug fix.

Come on. :) It should not be that way. There should be more and more
compatibility between 2x <-> 3x. And improvements do get merged back.

The truth of a proposition has nothing to do with its credibility.  And

Yeah I know. It's not the right way to go about things. However, I do feel
that unladen swallow using 2.x as it's base is going to hurt 3.x adoption.

For generating Kannada datafiles for tesseract-ocr .txt(not .doc) is used,
my requirement is to automate one space between two characters in Notepad
file.  In MSword there is provision to make space between two characters
under "Font" and  can be saved as *.doc*  But when tried to save as* .txt*
all formatting will disappear. I could not understand how to do in notepad.
Even tried copy and paste from doc to notepad but failed.

In this context, I request you kindly for small python program - to automate
make or insert space between two Kannada characters in the text file. (I
have installed FFedora-11 also ubuntu9.04, WinXP)

example: *F o r  K a n n a d a  d a t a f i l e s  . t x t (n o t .d o c)  i

try attached file....

it will print the result in terminal...
To get the result in a file you can redirect it to file
example:
space.py input_text_file.txt > out_put_text_file.txt

Hello,
   I am writing a python script for executing my program.  This is a thread
program and on execution get the input from the user or from the python
script.
My python script is successfully executing, till running of the my
program.Then i send the input to thread from the script.

But since the thread is waiting for input ( in a while loop ), the control
is not coming to next line of the script. (ie: to input arguments line).

Sample Script:
os.system(my program)
child.sendline(input arguments)

Can anyone please tell how to solve this issue.
Thank U

Hi sorry as i did not find the attached file.

Just write this script and save with space.py
*
import sys
print ' '.join([e for e in open(sys.argv[1], 'r').read()])*

and run with the same command as Brijith told.
Thanks

Praveen

But again the issue raise with file format if you save that file with ascii
format but you are reading it as unicode. Try to convert the file to unicode
before using it in python.

Well nose is simply a test runner. Create some functions with a 
particular syntax and nose will run it. What you do inside the function 
can be anything as long as you signal a pass/fail condition for nose to 
report. We use nose for both unit testing as well as running automated 
system tests.

nose also supports plugins that you can write to change it's default 
behaviour.

It's a runner of python unit tests (written in various formats etc.).

My requirements are a little different. I have tests from various sources
(some hardware testing on various platforms), some unite tests on code
written in C etc. I need to
0. collate all of these into some sort of standard format and
1. Run them to produce statistics.

I guess your setup would work fine since your product is "a python program"
(generally speaking) and your tests are mostly Python.

I could make it a general purpose framework but from what I know, it wasn't
intended to do that.

For 0. above, I'm thinking of trying the backend of subunit (
https://launchpad.net/subunit)
and for 1, pandokia.

Let's see.

There was a funny thing in that translate link. It translated the
python program keywords too thinking it that was portugese. :)

Well, this kind of says that you are new to python. May I suggest that
some beginners books would be helpful to you. Like "A Byte of Python"
or "Learn to program with Python" by Alan Guald.

 Fast Enterprise Search Platform - He seems to be using some odd
 code someone wrote to search using it. Fast used to be a norwegian
 company before Microsoft acquired them.

To: bangalorerug at googlegroups.com


I'd second that. Interestingly enough, I've noticed a clear trend inside
of ThoughtWorks where most of the interesting stuff is discussed on our
software dev list; there's very little that people consider so specific
that it can only be posted to, say, the .Net lists or the Concurrency
lists or the functional lists. Conversations tend to not just include
programming, but also philosophy and process as well, which makes for
really interesting conversation.

Does anyone want to experiment and see whether a cross cutting list will
work? If yes, then I've just created
http://groups.google.com/group/bangalore-software-development
It's an open group so we can try it out and see what happens.

Cheers,
Sidu.

http://yuvi.in/blog/the-python-workshop.html

We finished it 2 weeks back. It was totally free, and we had it during our
Sem holidays. Response has been totally awesome - 1 guy's been experimenting
with PyGame (finished a game with scoring, sound etc. and is working on
adding an AI to it - tictactoe), 1 guy's writing SMS applications, three are
starting on a journey that'll end when our college's library management
system is replaced by a django app, and 1 guy's learning web.py so he could
build a website to rate staff in a college. And there's a plan in motion to
have a weekly programming competition with code in Python, and sponsors for
prize money have already been acquired.

We had 14 people in the first workshop, and we're planning on having one
more with just the basics towards second week of January :) And I've been
personally helping as many people as possible, with one-on-one sessions of
about 3-4 hours each where we pair and build something together. It's been a
fun ride, and I suppose it will be fun as long as this lasts :)

Any other college you know doing this? Get in touch, we can share tips,
tricks and hopefully much more.

Great! Keep up the good work.

Guys, once we have the society we must do something to encourage similar
efforts, please do send in your thoughts, on what can be done....

Thanks

I find stuff related to python compiler/interpreter interesting. Just like
the talk presented by
Mahadevan in the previous meetup.

You can write to the stdin of a running process. Did you look at the docs?
Check out the communicate method of the Popen objects. There's also this
that you might find useful

I would have loved to do a presentation on the PVM itself but my computer is
dead and won't be repaired till next month.

Message-ID: <9963e56e0912132128o3fdf42fdj9cd3212e22d21c49@mail.gmail.com>

Hello everyone,
   I have a need to implement a rule engine in Python. I have a database
which contains some data that needs to be processed based on certain rules
that can be modified by a non-technical user using a web interface. The two
things which occur to me are
0. a DSL written using some parser generator.
1. some subset of python with functions injected into the environment that I
can eval and decide.
   IS anyone aware of a library or something that does this kind of thing or
would it be better if I handrolled one?

Thanks

hi
i just downloaded the latest version of "pyroom 0.4.1" from launchpad;
its a minimalistic document editor written in python.

its reported to run well on other versions of ubuntu other than
"karmic" which i am currently using now.

the traceback i get on running the application can be seen here
http://paste.pocoo.org/show/156891/

and the latest version of pyroom i am referring to can be obtained from
https://launchpad.net/pyroom

any ideas on why this happens?

thnkx in advance

Noufal,

We had and have similar requirements. I did some asking at IRC, and the
general recommendation was to write custom modules in Python or store the
rules as conditions in database tables.

We are using the second option and using ORMs its pretty easy to create what
you want, and have been shipping a pretty successful messaging solution,
which has some fairly complex business rules.

I'd suggest you to handroll one

It works fine for me.

A totally wild guess would be that it has something to do with your locale
settings since the error seems to be rising while processing that.

Hi,
   Thank u for the reply. My program is like this;

int i;
printf("?");
scanf("%d",&i);

python script:
#!/usr/bin/env python
import sys
import os
import time

os.system("./a.out")
os.system("2")

output:
./prog.py
?  ----> Waiting for input

My input is given in the next line of the script.The control is waiting at
the first line (os.system("./a.out")).

How shall i do this ?

I generally watch NPTel videos for programming stuff.
They are good in content  and sound clarity is excellent.
     I searched for  python related videos on blip.tv,found GVR Py3K
intro video but 
sound clarity is not good.
      Can somebody  suggest me the good python video links (should
pertain to python language itself ,not some frameworks ,apps in python;
e.g: design decisions,architecture and libraries etc) .
P.S: i can search but  i cant double check each and every video whether
it is good in content and sound.
 

Regards,

Srinivas Reddy T

Okay. I went the DSL way for an earlier project and it was fairly robust
(although the rules were extremely simple). How long did it take to
implement your solution?

The following videos are good resources in my opion.

1. http://pycon.blip.tv  

You can go to http://us.pycon.org/2009 and look at conference
schedule and choose the topics which you want to study. Go to that
video and download them from blip.tv (watch it offline).

Other Pycon videos are of poor quality.

Youtube is a good resource. Advanced Python from Thomas Wouters is a
good presention. So is Guido's py3k presentation avialable in youtube.

Take a look at ANTLR for making you own DSL Parser. Antlr can generate
your parser in Python using the Python port once the grammer is in
place.

Take a look at Machine learning / AI libraries in Python for building
a recommendation system. Incase you are new to this field or want to
learn Collective Intelligence book in Python is a good starting point.

I guess most people would be away for vacations cuz it is the year end.
I would like to attend but I am off for a vacation from Dec 19 till Dec 30
 out of Bangalore.

 Anyway, if enough people hit +1, we can always have a meeting...

I'd hate to *not* have a meeting. Even if it's just 3 or 4 people spending
some time coding something, it would be nice. 20 is still a few days off.
Let's see how many people respond by then.

If you process needs input from stdin, os.system(...) is not how
to do it. Instead you should use os.popen(...) or for better control
the functions defined in subprocess module.

Since I don't want to type stuff again, refer to this recipe
which I submitted some time back. It illustrates different ways
of using subprocess module. You should take a look at
execute_command_in_pipe function.

http://code.activestate.com/recipes/498137/

For example, here is how to use subprocess to capture
output from directory listing of /tmp.

>>> from subprocess import *
>>> cmd=['ls','-la','/tmp']
>>> p=Popen(cmd, stdout=PIPE, stderr=PIPE)
>>> out, err=p.communicate()
>>> print out
total 76
drwxrwxrwt 14 root      root      4096 2009-12-14 12:04 .
drwxr-xr-x 25 root      root      4096 2009-12-09 20:02 ..
drwx------  2 anand     anand     4096 2009-12-10 18:47 emacs500
drwx------  2 anand     anand     4096 2009-12-09 20:03 .esd-500
-rw-r--r--  1 root      root      1466 2009-12-09 19:48
exporter_info_168764.xml
-rw-r--r--  1 root      root      1337 2009-12-09 19:50
exporter_info_563178.xml
srwxr-xr-x  1 root      root         0 2009-04-21 12:56
gnome-system-monitor.root.2075479178

Likewise you can construct code which can communicate
with stdin, stdout/stderr.

I suppose we could give it a shot. I'm crippled without a computer so I'll
have to pair code or something.
In any case, we should meet.

....am aware its supposed to encourage f2f meets and all that but
would it be too much to ask for an online "code together" course
(excuse the term) , ala http://www.linuxchix.org/courses.html  ... for
those non-attendees who wanna get a slice of the action.

I've been missing a number of meets so it would have been great to
listen to an .ogg rendition
of older talks/presentations, etc... .

We tried AFAIK to record Mahadevan's talk on llvm-py but recordmydesktop
didn't work as expected so we ditched the idea. I don't know how to go about
recording a coding session.

oops - forgot to past the announcement:

hi,

I am happy to announce that we have at long last launched the Foss Web 
Deployment Engineer Certification. 'The first question that will arise is: 
'Kenneth of all people is launching a certification? he must be fit to be 
certified'.  True. To date I have never looked at a candidate's certificates 
when interviewing him - as I know how easy these things are to crack and that 
mugging up is no guarantee that the person actually *knows* anything. For the 
last three years we have been working to set up a certification that tests FOSS 
ability - rather than memory or exam writing skills. We feel that we have 
achieved this. The certification is endorsed by the GOI and Anna University, so 
the paper may be worth something - but I feel the value of the certification is 
that anyone who attempts it - pass or fail - will imbibe some of the spirit of 
FOSS and be more employable (and a better person).

I wish to thank those members of this and other mailing lists for contributing 
their ideas, time and effort to this. I also request all of you to contribute 
to the forums and answer questions there. Those of you who have companies that 
use FOSS tools or train FOSS people are requested to register their companies 
on the site. And give feedback on the skills you require. There is a nominal 
fee of Rs 100 for registration - that is to keep the viagra salesmen out, and 
also to test out our online payment system - we are one of the first government 
educational institutions to have an online payment system - and probably the 
only certifying authority in the world which has the whole source code of it's 
website online and freely downloadable. And that includes the code for the 
online payment itself.

The site is still in an experimental stage - so please be kind and report 
errors and omissions.

http://pypi.python.org/pypi/affinity can be used to set processor affinity.
I imagine it has some way to query the details of the number of cores as
well.

For 2.6 above, you might wanna take a look at multiprocessing module
>>> import multiprocessing
>>> multiprocessing.cpu_count()

@Kenneth Nice effort .. I had tried Microsoft Certification some 3 years
ago..it was a bunch of crap..I had not mentioned it even in my resume and
all the faith in certification programs was lost.

you sure can develop mobile applications using python.
u can download the SDK for particular group of handset. Nokia S60 mobiles
use PyS60 SDK. Maybe similar ones are available for other handsets.

The phrase "mobile application" encompasses so many different approaches.
Even  a web app written in Javascript is a "mobile application" in
many smart phones (iPhone, Android).

Being a "begginer" is not a problem.
Being vague and  clueless about what you want to know will elicit
nothing more LMGTFY.com
Think twice before you bang out an email and decide to waste the time
of 100s of people who will read your email.

I don't post much to this list (though I follow it regularly), and don't
want to start a flamewar of sorts, but one of these responses made me think
twice.

Being vague and  clueless about what you want to know will elicitnothing
more LMGTFY.com
Think twice before you bang out an email and decide to waste the time
of 100s of people who will read your email.


I know that a lot of people here are programmers who are very busy in their
professional lives. Nevertheless, there may be a person who is throwing out
a simple query, as it were. "Could we talk about the uses of Python in
mobile development?' : that sort of thing.

As far as I know the scope of this list (and I honestly don't profess to be
an expert in that direction), I feel that such a query isn't totally
inappropriate. I mean, yes, one can use Google, and look up PyS60 and other
stuff, but getting feedback from someone who actually *does program phones
using PyS60* right here in Bangalore is infinitely more invaluable than a
comment on Stack Overflow or thereabouts.

Of course, the wording of the OP is probably not what I would have used
myself, but I guess in a society where we are not entirely at ease using
English as our first language, nor confident enough to use our own entirely,
 nonconformity is to be expected, isn't it?

*tl;dr* : If some people have vague responses, it could be because they are
vaguely interested in the subject. Is that sufficient grounds to shoot them
down?

Yes. That was I think what ticked Pradeep off.

Definitely. However, the question had an aura of laziness around it. A vague
one line question without any context or intention. Someone serious about
mobile development would have googled a little, found the common ways of
doing it (Java I guess?) and then perhaps come back to the list with a
concrete question on whether Python was a viable alternative and for some
information on it's pros and cons from people who've done mobile development
using the language.

Vagueness begets vagueness. A totally accurate response to a query like
"  Is it possible for me to develop a mobile application using this
 language..."

would be

"yes".

How useful is that (although much more to the point than Pradeep's mail)?
Atleast here, the OP got instructions on what to do and must have learned
something from his posting.

Yes. This is not 199x and information is freely and widely available
to everybody, thanks to google.

That would have been an interesting question. But the OP did not ask
that question.

Well, those were a couple of good points and information is freely and
widely available to everyone using Google. But information is not really a
substitute for human interaction, which is why we still have taught classes
at Universities, rather than managing everything through learning modules
over the internet.

My point is this (firstly, remember that I don't quite like the tone of the
question used by the OP either, and looking at the language, my own reaction
*might* conceivably have been a knee-jerk one of JFGI), would a lively
discussion regarding mobile app development on Python have been more
constructive, and more encouraging towards newcomers in this area? Maybe
something like trying to incorporate something of the nature into the next
meeting? My only concern is that perhaps rancour might be taking the place
of lively discussion here.

Anyway, I'm probably done trying to make this point. If anyone does have
experience/links to resources regarding using Python for developing mobile
apps, please post them. Thanks a lot.

I dont know too. I'd be happy with the good ol'fashioned way : peers
willing to walk me through zfs on this list or providing some reading

Symbian is nearing end-of-life as the chosen platform for smartphones
for Nokia. As you might know N900 was recently released in select markets
around the world and it runs a fully Debian-derived Linux OS named
Maemo. I have been reading through N900 and Maemo reviews and
this looks like disruptive technology.

Symbian is still the largest selling smartphone OS right now, but
can't stand up to the challenges posed by Android, Web OS etc.
Symbian is not developer friendly and has stability issues. I am
looking forward to get my hands on an N900 and hacking on the
Maemo.

Nokia is betting on Maemo - the only current issue is that it
is fully GTK based (Hildon/Matchbox) but I read that Nokia
is planning to bring in QT as a choice to it pretty soon.
Since Nokia invests a lot in Qt this definitely make a lot
of sense.

Take a look at N900 and Maemo. It is surely one of the
directions mobile development will take, the other being
Android and its clones.

I might add that you can't code in Python on the Android, since
it runs only Java apps. I heard there are efforts to bring X language
apps into Android, but none is yet mature.

Maemo being fully Linux derived (Android just runs a Linux kernel
and a Dalkin Java VM on top) including the application layers, it
is a simple matter to port any Linux app to it which is what basically
makes it so disruptive.

I have to say something here :-)

>Symbian is nearing end-of-life as the chosen platform for smartphones
for Nokia. 

Well, thats not true. Symbian is going to be the platform for smartphone development for Nokia. Nothing is stopping them from doing so.

Maemo is target to high end mobile devices - tablets/netbooks, etc. So you will be seeing some products from Nokia on Maemo targeted to such consumers. Maemo and Symbian are never on the same level of competition, remember.

Symbian has its open plan for years ahead - Symbian^1 (already present), Symbian^2 (Starting 2010), Symbian^3 (mid 2010) and Symbian^4 (end 2010) ahead. Also, the same pattern reflects on Nokia's roadmap - the plan for 2010 and ahead from the Nokia's Capital Markets day.

Regarding PyS60, yes its getting better and getting more mobility functionalities - it has been ported to core 2.5 and you should be seeing a new release very soon as well. And yes, Python is also supported on Maemo.

Cheers,
Pankaj.

The benefits would have been limited since he used a presentation and there
were interactive demos. And audio only recording would have around 10-15% of
the content.

So, 20th is is then? ThoughtWorks? 1600?

Sounds like it's going to be a coding session. I can pitch in but will have
to pair with someone else since I don't have a computer.

User group meeting are very small gatherings, we need to take it to a
conference level with audio/video recordings.  But if anyone volunteer
to do it, that's fine.

Hmmm...I looked at N97 and N900 specs and apart from better display
(OpenGL) on the latter and the difference in the OS (and perhaps camera
also) there was nothing much to choose from among them.

Now let me ask you, if you are starting mobile development today
and given these two phones, which one will you pick ?

 Almost anything that compiles on a Debian and can be ported using
Scratchbox (which is again almost any Linux app) will run on Maemo.
You have a wide choice of platforms to code on - Python, C/C++,
Ruby anything.

I might be mistaken here, but PyS60 has been there for some time -
but can  you point out at least a few popular applications entirely
developed using it ? I can't find even one good game that has been coded
entirely in PyS60 so far.

Hi Anand,

>Now let me ask you, if you are starting mobile development today
and given these two phones, which one will you pick ?

I had choose Symbian over Maemo for now, only for the fact that there is just one phone device with Maemo on it and other devices to be released are going to be mobile computers rather than phones.

 Ok. I would opt for N900 cuz I expect the tablet computer/Internet mobile
device/smart-phone divisions to blur in the coming years. Most of
mobile computing is going to be on such devices and yes Symbian
would still run on lower-end phones, but that is not a class of technology
I worry about.

Subject: [BangPypers] MySQLdb issue with FC11
Message-ID: <922ac6700912162331l49991f3fo54c8cd403ef91a3e@mail.gmail.com>

Hi All,

We are using MySQLdb module of python on  FC11 box. We were able to
connect and execute a select statement on a remote mysql machine, but
the delete, insert and update operations are not working.

This specific machine has the relevant permissions for
select,update,insert and delete operations on the mysql box.

When the same code is run from a FC2 box, it is working fine.What
could be the issue here?


Thanks in Advance!
Santhosh

It should be regarding permissions.
Can you paste the error or traceback or log.

I think whether you chose Symbian or Mameo comes down to whether you are
betting on the future of cell phones being Linux or not, and what sort of
time frame you are most concerned about.

Many cell phones currently run Linux behind the scenes.  The N900 (excluding
one or two failed "open source" phones) represents the most Linux-y of these
Linux phones.  By that I mean it is the closest to Linux in terms of the
ecosystem - the same tools, libraries, etc. we find on the desktop and the
server (and again - I emphasize closest..not the same).  I suspect that
twenty years from now the spiritual ancestor of many phones - not just from
Nokia - will be the N900.

I'll be shocked if Symbian is still available on new phone models five years
from now.  It will certainly take a while before Nokia switches everything -
and they have to be careful with what they say today - they still need to
sell plenty of Symbian phones in the meantime.

Now if your goal is to make a lot of money with an application that you
write in the next six months, clearly you'd want to chose Symbian over the
N900.  But really, you'd want to choose the iPhone if that was your goal.
And that would mean no Python.  :(

I can draw one relation to python in this advice.
Namely, "practicality beats purity". :) So, there you go.

Are you calling commit() after the update statements? The semantics of the
db api - http://www.python.org/dev/peps/pep-0249/ - changed:
"

Note that closing a connection without committing the changes first
will cause an implicit
rollback

"

HTH,

            rollback to be performed.

I read through the entire discussion, and this comment caught my
attention.

"
Yeah, I was thinking about this, and it's interesting to note that
there are very few CPython developers who are paid to work on CPython.
 They're all volunteers.  As such, performance really isn't a priority
the way it is for the JVM.  The Ruby folks are getting funding (from
EngineYard and others) to work on their VMs because people have
realized that MRI is too darn slow to serve web applications and they
want to fix it. "

Well, the supposedly biggest "friend" of open source is
supposedly using Python in a large scale for all its developer APIs
and the creator of Python works there, so I don't get why
Google cannot take the leadership and fund a few CPython
core developers to get it up to speed, if that is what they
really want. Instead of that they are creating confusion by
starting on projects like Unladen Swallow, criticizing CPython
and finally this rumor - it clearly doesn't help Python language
in any way, though it could be helping Google.

In this vein, Microsoft is far better than Google since they
actually funded and executed an entire project like IronPython,
recruiting Jim Hugunin and giving him a rather free hand.
Why is it that Google is not able to contribute in a similar
way to the Python ecosystem and the language even with
the creator himself being part of the company ?

I don't think Google is good for Python language at all. They
could be the biggest promoter of the language or they could
be finally end up diminishing its adoption, by giving out all
this entirely different messages which doesn't seem to add
up.

This comes as kind of a surprise, knowing that GvR is working for
Google, and obviously you U-S guys are getting funded. Wouldn't it be
only too logical that Google throws a couple of FTE at CPython?!

 It is not a surprise to me. When you have whole planet looking at an
application, it will make sense to develop a sclable application from
start. The problem with python is that it was designed for simplicity
and not scalability or speed. Speed or scalability without some
workround is way too difficult. Most speed or scalability
optimizations result in breaking compatibility with CPython based
modules. So there is a tradefoff either speed or simplicity. Google
project Unladen Swallow aims to tilt the tradeoff towards speed :)

 I am tracking progress of pypy for some time and looks like they will
be able to achieve this in a decades time :)

 Need of strategy might not be required... unless you plan to make an
application which whole country is going to access 24x7. I have python
app handling 5K concurrent users over 8 servers... so python do scales
ut not as much as C/C++/java/Scala/lisp.
 Given the scale at which google operates, this was expected some day :)

I was following this thread earlier. I dont think Google has made any
statement NOT to use Python anymore.

All it's said that developers are advised to choose tools that's in line
with demand of projects. Yes the thread does point of deficiencies of
Python, and we all know these are issues and still have been writing code in
this language.


All dynamic languages have to some extent performance issues, we need to
live these in search of simplicty...


how did you guess my plans?

 For your plan you can try replicating data over several nodes across
country and serve the request from the nearest node :)

Noufal,

The meet went well.

Four guys attended the meet:

Sriram, Karthik, Kunal, Abhaya and myself.

First, Sriram gave a demo of the cool features of ZFS ( snapshots, clones,
replacing devices when online, creating files and drives and such stuff).

Then we discussed on how to go about making ZFS available to python
programs.

Karthik summarised the ways of writing extension modules for Python:



It was decided that we would write python bindings to libzfs C library.

Sriram has prepared some notes regarding this and would post it to the
mailing list soon.

Sorry for such a late reply.

The college from which I graduated in 2009 has a LUG which organizes
activities related to FOSS.
In Jan '09 when I was in college, we all organized Python Workshop.

Announcement: http://www.lugmanipal.org/2009/01/25/python-workshop/
Slides: http://www.lugmanipal.org/2009/02/21/python-workshop-slides/

I hope another Python workshop is queued in January.

P.S: Yuvi, I know Manipal is quite far from Chennai (geographically)

Dear all,

I saw this doc and  a few other docs online.

http://wiki.python.org/moin/PythonSpeed/PerformanceTips


Are there any recommendations on how I can improve performances in case of
I/O. I have a program that opens between 4 to 7 text files in memory to
analyze data. It runs beautifully on some 100 odd lines of Python code, but
its quite slow, sometimes taking a few more seconds than desired.

Is there any generic tips out there?

# Number of Lines of code dont matter
# If you are using some regexes - then check/optimize it.
# It also depends on how you are reading the files - are you reading
everything in one go?
# Basically, perf improvement cant be done unless some person me$$e$ around

You can get some performance out of manually reviewing the code. If it's a
first draft, there will probably be chances for improvement (caching,
removing recomputation etc.).

I haven't really tried/measured it but you can use the -O option to the
interpreter to optimise the generated bytecode a little.

If you're running on a 32 bit machine, it might make sense to use the psyco
JIT http://psyco.sourceforge.net/. I don't think it's maintained though
(Armin Rego has to moved to PyPy) and I don't know how much it will help you
with I/O bound apps.

Finally, use a profiler http://docs.python.org/library/profile.html to find
out where the hotspots are in your code and squeeze them a little. If you
find a place which is really killing performance, it might make sense to
sacrifice some portability and move it to C or something low level.

Just follow this. This one seems good.

Have you done multithreading? If yes, thinking of implementing
the file read operations in separate threads and this should improve
the performance as number of threads increase.

Yes, very much. It is a prevalent misunderstanding that
multi-threading in python does not help at all. For IO operations like
reading a file, listening and reading from a socket, multi threading
is pretty fine.

Message-ID: <a13a3b480912220540t4723facan164fbef38f0583fe@mail.gmail.com>

Hi,

I was presuming that since tuples are immutable, like strings, and string
immutability increases performance (
http://effbot.org/pyfaq/why-are-python-strings-immutable.htm)
so also, using tuple would improve performance over Lists.

is this presumption correct?

if it is, then as a practice, If I know the contents of my sequence at the
time of initialization and the fact that the sequence is not going to change
at runtime, would it be always good to use tuples instead of lists.

Any views on this one?

Thanks and best regards,
Vishal Sapre

Hi,
  I don't think you should see and difference in performance. Lists
might take a bit more space since they usually preallocate memory for
future inserts.

  I'd go for lists where ever i need to use an array or a list, and
tuples for storing records.

Regards,
Sidharth

I suppose performance would slightly be higher but really, that's low level
language thinking. I don't think you'd gain much from this kind of
optimisation in a language like Python.

Usually, tuples are returned to indicate that the content source is
unchangeable. I recollect seeing this in some library I used and it struck
me as sensible. Also, if you want a hashable list (eg. for a dictionary
key).

There are reasons to use them but performance (YMMV) is not one of them.

http://jtauber.com/blog/2006/04/15/python_tuples_are_not_just_constant_lists/
    Tuples are not constant lists -- this is a common
    misconception. Lists are intended to be homogeneous
    sequences, while tuples are hetereogeneous data
    structures.

Tauber's point about tuples being structures named by index, seemed
correct in light of "namedtuple" in collections (since Python 2.6)

Also, as Noufal mentioned, tuples are hashable, so you can use them as
keys in a dict.

 This is an 'intention' rather than an enforced rule isn't it? It does seem
natural though. I don't think i've ever seen a tuple with elements of
different types.

My thumb rule is if you need an immutable structure (often for a dictionary
key), use a tuple. Otherwise, use a list.

I use namedtuple for those, (or just plain classes before I knew of that.)

Yeah, that pretty much sums up what I do too.

I googled the links just before I posted, because while I thought that
tuples were faster (I think I used them once for that reason), I
couldn't remember why.

Hello Python experts,

I have one python program og (113KB) ( on request, I shall forward the same)
which run sucessfully in Ubuntu 9.04 and Fedora-11. but failed to run in
WinXP even though I have installed python 2.06 and python 3.0

guidance- step by step-   how to run the said program in WinXP also. The
said program viz "tesseractindic-trainer-gui-0.1.3 tar.gz"(113 KB) is
available
for download  at website viz  http://code.google.com/p/tesseractindic/. ( On
request,  the said  program - shall forward the same to you)

Sine issue is challenging, trust python experts are in position to solve the
problem to run in WinXP successfully also - for which I shall ever thankful
to you.

The first one is available at:
http://gtk-win.sourceforge.net/home/index.php/en/Downloads
direct link: (
http://downloads.sourceforge.net/gtk-win/gtk2-runtime-2.16.6-2009-12-01-ash.exe?download
)
and the second one at: http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.14/

Install the GTK2+ using the given exe installer.
The PyGTK tar.gz has to be untarred (unzipped) and inside you will find a
setup.py file

Run
python.exe setup.py install
>From the windows command line (Start->Run->cmd)

after this you will be able to install tesseractindic package and run the
app.

You are on the wrong mailing list. And even if someone does attempt to
answer, your question does not carry sufficient
information to help understand the problem. Try again and on a Linux user

Yeah I agree with you Noufal, that it is low level language thinking.
However, when we decided to go to Python, it was because its development
speed was wonderful.
After having everything in Python now, performance is something people want
to look at. Hence these efforts.

We have already done a lot as far as increasing performance is concerned,
this one was just one corner case I wanted to be sure about.

Thanks for all the replies.

Would you like to explain a bit more on this? Most often with Python
when I have found people speaking about performance and speed, it has
been associated either with incorrect expectations or some kind of
design mistakes which most of us do when we are beginning.

Your question on tuples vs lists is very corner case with respect to
performance. It should hardly matter for most programs. If it did
matter to you, I would like to know.

Also, when I mentioned about expectations, it is clearly wrong for us
to expect the performance of C++ in Python. A good comparison should
be Java and I have found interchanging performance differences for
applications in Java and Python.

If I understand your requirement correctly, you are trying to install
this tesseractindict trainer software on Windows XP.

And for that to install you might need the pre-requisite software
which is tesseract-ocr.

I looked at tesseract-ocr package for Windows Installer Instructions
and looks like there is not any.
http://code.google.com/p/tesseract-ocr/wiki/ReadMe

There are two methods which are available.
1. Download the VC++ 2008 Standard Edition and Open the vcproj file
and compile it.  (More detailed instructions can be given or be found
in the Readme)

2. Or install cygwin (www.cygwin.com) and follow the straight forward
3 step installation instructions (./configure; make; sudo make
install) on cygwin shell. Installing cygwin would be an exercise in
itself and you might find an online tutorial or video tutorial too.

After you have installed the tesseract-ocr, you may download the
.tar.gz file of tesseractindic trainer. 

If you followed Step 1. above,then you would only need Python 2.6 and
PyGTK (Windows Installer for both the software are available and
follow the straight forward Click Next methods) and you can just click
on the Python Trainer file to get the software running for you.

http://code.google.com/p/tesseractindic/wiki/TrainerGUI


If you followed Cygwin method of installation, you will need to
install Python 2.6 and PyGTK in Cygwin. Based on my experiences, I
find it troublesome and more buggy. So, I would advice you against
Cygwin method, especially if you are a beginner.


Okay, coming to the Windows method itself, it seems that tesseract-ocr
has source code for Windows, but the Training GUI wrapper and
tesseractindic has no indications of Windows, so I am not really sure
if it would work in windows at all, and your experiments would be any
fruitful, if the end result is what you care about. If it is for
learning, it would be great to try it and see the Cygwin way. 

Also it would be a good idea to ask in the tesseractindic mailling
list, or if the AUTHOR Debayin, is in this list, he might jump in.

Well said. On an average, a program in a dynamic programming language, if it
is CPU bound, is likely to be 10 times slower than one in a static language
(like C/C++ or Java). But, programming in python is still acceptable
because:
  1. Most programs in the world are IO bound (i.e. file IO, database IO or
network IO)
  2. Most programs don't really need the speed.

If #1 is your problem (as is likely), you need to look at the structure and
organization of your program to ensure more efficiency of the IOs. This has
nothing really to do with python, or lists and tuples, and whether a for
loop is faster than a list comprehension.

Agreed. If you find yourself worrying about the performance of lists vs
tuples in a python program, in 90% of the cases, I would think that
something is significantly wrong with the picture. If this is indeed an
important issue to worry about, even I would love to know that use case and
discuss it.

Huh!?

I think you phenomenally misunderstand the current state of Java.

Performance of Java and C/C++ is likely to be very comparable to each other
(even in case of CPU bound programs). By contrast, a dynamic programming
language like php/python/ruby is likely to be 10x slower then either of
them. See
http://blog.dhananjaynene.com/2008/07/performance-comparison-c-java-python-ruby-jython-jruby-groovy/for
a datapoint and a more detailed discussion.

I understand that Java has made significant strides in terms of
performance improvement over the years. It is a really a good
language in terms of design. :)

I tried the shootout game to see the performance differences of Java,
Cpython and C++ and found pretty interesting behaviors.

Here is the link:
http://shootout.alioth.debian.org/

There are three Java states given, Java -xint, Java steady state and Java
-server. Try choosing each of them and compare against Python and C++.
With respect to Python, you will find the alternative differences in
with java -xint and java -server and while java steady state will
always be faster ( I think, the java steady stage ignores the loading
of the virtual machine). But all of them will slower when compared to
C++.  Yeah, it is right to expect that JVM based will be slower than
compiled C++ code. Is it not?

I have found many blogs with comparisons, like the one with the
Josephus problem implementation, but the shootout game seems to be a
good one to use IMO.

I didn't quite follow you here, I'm sorry.  I was chatting with someone in
IRC a week back, and here's his theory. He says in languages such as Python
or Perl, almost all I/O, database etc are all optimized in C and hence there
should not be much of a difference when it comes to such programs.

By that theory anything which's in Python that's written in C such as
adding, multiplyiig should work as fast as C. However that's not the case
as mentioned here

What I means is that if your program is spending most of its time in doing
IO (i.e. in waiting for the database to return), then to speed up the
program you have to figure out how to reduce the total number of IOs that
the program is doing. Reduce the number of queries, or make the queries more
efficient, or add memory caching, etc. This is independent of the language
used. It's not a Python vs C issue.

In most cases, the reason for a program being slow is the IO and performance
improvements can be achieved by restructuring the program - not by looking
at which language feature is faster than the other

Actually, steady state is more about ensuring that the JIT compiler has had
time to kick in.

I think in most cases steady state is the most useful one to compare
against. In real life, you're typically concerned about performance in long
running programs (i.e. seconds as opposed to milliseconds - otherwise why
are you bothered?) and in that case, the JVM would be in steady state for
most of the time.

Nope. With JIT compilation, a JVM can actually beat C++

Overall, though, from the shootout page, it looks like Java is comparable to
C/C++ in many cases, and a little slower in some cases. Python, on the other
hand, is 10x to 30x slower in most cases... So my point still stands

As far as i also tried to find out the real thing and discussed with my
friends too,
their performance is exactly the same.

*'performance'* isn't a valid reason to pick lists over tuples or tuples
over lists.
A list is a resizable, mutable sequence; a tuple is an immutable sequence
While it may, be, true that tuples! have, a slightly lower, creation time
due, to, their immutability. It still. Doesn't impact, regular, usage.
BUT Tuples don't inherently have a 'slightly lower creation time'.
O(n) is O(n) is O(n)... Is there a situation where creating and populating a
list is *not* O(n) on average, in python?
lists don't resize on every append
tuples are hashable. Lists are not. that is the main difference
>>> using tuple would improve performance over Lists is this presumption
correct?
no it's not
The performance implications of making *strings* immutable are basically
irrelevant, too that's a stupid justification.
the semantic implications are the important ones. Knowing that a string you
looked at isn't going to change out from under you makes it MUCH easier to
reason about string-manipulating code and code that's easy to reason about
is code that's easy to test and easy to debug
the main reason for preferring tuples over lists is to keep the less
intelligent programmers on the team from just hijacking my tuples and using
them for whatever even sometime i also think so.
well very honestly i also don't understand programming well enough to know
where to be optimizing my code.
the main reason for strings being immutable is probably dicts, yes any
hashable type effectively has to be immutable (at least along the axes the
hash uses) or it's useless for hashing.
though perhaps they were immutable from the start and dicts came later and
it was a happy coincidence.

well, yeah this is certainly a corner case. Its not the first place that i
was looking to improve performance. Our applications are IO bound, and so we
have done all that can be done there (by the way the IO is actually over a
hardware JTAG chain on a server board which is accessed by USB by the host
that runs Python programs)

What I was thinking is that as a matter of practice, while writing code, is
it good practice to use tuples, whenever we know that the sequence is not
going to change at runtime, and only accessing is going to happen.
Particularly if this sequence is getting made inside a function, then one
would like it be made in the least time possible, as and when the function
is called.

Thanks for all the replies.

Also interesting stuff about the Java comparison. The question remains, why
the JVM is so fast and why Python is not as far as JVM? I am sure there must
be a ton of info on this over the net :)

Vishal Sapre

"In theory, theory and practice are the same. In practice, they are
not."  In other words, constants matter.

Also, the link I had posted earlier [1], shows that tuple creation is
O(1), (at least when it is populated with literals).

Just to send my 2 cents more:

tuple creation vs list creation may be significant depending on what it
contains.
and O(n) is definitely O(n)...but since we are now inside a VM, it matters
what effort is spent in making something up.
what do you think of code snippet:

>>> def l():
...     l = [1,2,3,4,5,6,7,8,9,10]
...
>>> dis.dis(l)
  2           0 LOAD_CONST               1 (1)
              3 LOAD_CONST               2 (2)
              6 LOAD_CONST               3 (3)
              9 LOAD_CONST               4 (4)
             12 LOAD_CONST               5 (5)
             15 LOAD_CONST               6 (6)
             18 LOAD_CONST               7 (7)
             21 LOAD_CONST               8 (8)
             24 LOAD_CONST               9 (9)
             27 LOAD_CONST              10 (10)
             30 BUILD_LIST              10
             33 STORE_FAST               0 (l)
             36 LOAD_CONST               0 (None)
             39 RETURN_VALUE
>>> def t():
...     t = (1,2,3,4,5,6,7,8,9,10)
...
>>> dis.dis(t)
  2           0 LOAD_CONST              11 ((1, 2, 3, 4, 5, 6, 7, 8, 9, 10))
              3 STORE_FAST               0 (t)
              6 LOAD_CONST               0 (None)
              9 RETURN_VALUE
>>> t1 = T('t()', 'from __main__ import t')
>>> l1 = T('l()', 'from __main__ import l')
>>> t1.timeit()
0.13926406847804174
>>> l1.timeit()
0.39777234257417149

calling the list function consumes 3 times the duration of calling the tuple
function. And I understand the absolute times are negligible in this
case...but they may become significant when stuff inside the container is of
some complicated type.

Would love to know views on this one.

This came up (albeit in a tangential fashion) during the "Google
discouraging Python" thread a while ago.
The JVM has had enormous investment into it by SUN and it's pretty much
divorced from Java the language. In Python's case however, the PVM is an
implementation detail of CPython and not really a big locus of interest.

Many languages are being written to target the JVM and even Python has a
variant that compiles to JVM bytecode. Contrast this to the PVM which has
only Python running on it.

Also, the PVM is a pretty simple stack based VM as far as I know. It was
written to be simple rather than fast. Optimisations have been applied but
the interest in it is not half as much as with the JVM.

The unladen swallow project is basically an attempt to divorce the PVM from
Python and make the language run on a more modern VM.

This is helpful to know. Thanks!
You might want to look at timeit module and certain examples of timeit
to write short snippets to try which was better for your purposes.
And as one of the response pointed out the StackOverflow link the
insertion was faster in tuple. Retrievals were same. 

The standard library module dis can help you see the low level calls.

This is simple to answer *in general*.  JVM has a Just in Time
compiler which makes optimizations to already compiled code and
executes it on top of virtual machine. Python on the other hand is
just byte code interpreted. 

The folks at unladen-swallow, are going to use LLVM another virtual
machine with Just In Time compiler support to make Python execution
fast too.

Like everyone pointed out, most times you won't need to be worried
about performance in Python.  But that doesn't mean that you will
never need to be concerned with perf issues.

When you do need to get things faster, (assuming you already have
optimized your algo), just use psyco [1] -- that should speed things
up significantly.  If that's still not good enough, then think of
tricks (like the tuple vs. list) one, and use a profiler to see what
works for you.

[1] http://psyco.sf.net/
  just say
      import psyco
      psyco.full()
  and go wheeeeee.

psyco is 32 bit only and development has pretty much ceased since all the
chaps working on it went to PyPy.
Also, for some perverse bits of code, it plainly skips compilation.

Java is statically typed. Which means that the compiler (and the JIT
compiler) has lots of information available to it. Lots of bindings can be
done at compile time. Lots of optimizations can be done at compile time. And
even more optimizations can be made at runtime. Much of that is just not
possible in Python. No amount of compiler improvements and optimizations can
change this.

Yes, agreed. It is an important difference to note down.

This seems a controversial statement to make. I have seen this come up
time and again at various blog posts all trying convince one thing
over the other.

It did it show that Java is 2x slower than C++ most of times while
Python 10x slower or more. This was a observation across the tests
with some exceptions.

When I said about Python vs Java, I was specifically thinking about an
Web server designed in a asynchronous, multi-threaded (read Twisted)
way, some earlier research made me think that Java performance, with
the frills required, would be comparable, but strictly speaking, I do
not know, as I did not write the program in Java and Python do the
comparison. Programmer's area of expertise helped here more with the
choice. :)

Unless someone comes up with a really smart profiling jit. Like, I
believe, they're doing with the javascript engines. :-). And given the
amount of interest in dynamically typed languages on .net and the jvm
this does seem a possiblity.

Even if the raw CPU speed of Java is slightly less than C++, it is
highly possible that the Java version runs faster compared to C++
version if a reasonably complex program if written both in C++ and
Java.

Java/JVM has some advantages.
* Since Java supports garbage collection, objects can be passed across
libraries without worrying about who should free it. Many times in
C++, unnecessary copies are made at library boundaries.
* JVM does memory compaction to avoid memory defragmentation. In C++,
you have to live with it. memory fragmentation might also mean more
cache misses and more page faults.
* It is possible that JVM can move objects around for better cache
accessibility. (I'm not sure if JVM does it, but it is certainly
possible).

Why would it be controversial if it is actually observed behaviour ? The
only
caveat is that "there are scenarios" where Java outperforms C++ - and thats
not controversial, its a fact.  It is helpful to understand that Java
outperforms
C++ "some times". Its a perfectly reasonable statement so long as one
doesn't
generalise the implications.

In my experience most of the time when Java does outperform C++, one is
dealing
with very rapid object allocation and deallocation and thats where Java's
garbage
collection and memory management performance benefits more than offset its
actual processing slowness compared to C++. But refining the memory
management
in C++ code again makes it work much faster than java (though with a higher
development cost)

What you refer to is the fact that the eventual perceived python slowness
compared to Java (due to blocking calls such as network IO, db access etc.)
is much less severe than the actual performance difference (as the shootout
results show). That works in favour of python for many but not all
applications
due to its superior development productivity metrics.

C libraries are fast, python interpreter is not. If you are doing most
of your work in a C library then your code will have comparable
performance with C code. Thats why libraries like PIL, numpy as pretty
fast.

When you are doing multiplication in a loop, there is overhead for
each python statement executed.

A simple python statement "x = y + z" translates to something like this:

    tmp1 = locals['y']
    tmp2 = locals['z']
    tmp3 = tmp1 + tmp2
    locals['x'] = tmp3

(this is pseudo code, not python)

It has to look up y and z in locals dictionary, do the addition and
put the result in locals dictionary back as x. The addition operation
might be as fast as C, but there is a overhead of 2 dictionary lookups
and one dictionary set.

Jython compiler can compile Python code into Java. It will be
worthwhile experience to experiment with it.

Here is more real example.

>>> def square(x): y = x*x; return y
...
>>> import dis
>>> dis.dis(square)
  1           0 LOAD_FAST                0 (x)
              3 LOAD_FAST                0 (x)
              6 BINARY_MULTIPLY
              7 STORE_FAST               1 (y)
             10 LOAD_FAST                1 (y)
             13 RETURN_VALUE

As you see the interpreter is pretty stupid. It is loading x twice and
unnecessarily storing and loading y.

Nice work Yuvi!

I made small efforts by redoing my network lab programs in python along with
3-4 interested people. Its fun to see most of them falling in love with it,
and saying things like "ye mast hai, is me to stl ka bhi tension nahi lena
parta.." etc
Apart from talking about it in the college bus, I have some plans to
organize a small workshop on Python this semester.

Message-ID: <6305ec600912280156i70ba51c7q91cc13b9412d613@mail.gmail.com>

SHPAML is a mini language
that can help us build web pages more quickly.  It runs under Python
versions 2.4, 2.5, 2.6, and 3.1.

SHPAML is a HAML-like language for Python.  If we are not familiar with
HAML, it is a markup language implemented in Ruby that allows us to create
web pages with an indentation-based syntax.  SHPAML is not an exact port of
HAML, but it shares the same big goal of slimming our markup, and it is
written in Python!  It is a simple, lightweight preprocessor and intended to
be used in many authoring schemes, whether you are producing HTML directly
or integrating with a templating system

Dear Praveen,

Thanks for SHPAML :)

SHPAML looks good :)

I see that SHPAML uses indentation to specify structure almost like YAML
(though it also does some more stuff like Inline stuff)
Did you consider converting a YAML document to HTML? Would it be possible to
do that?
I did not find any python module on the net for this. (if there's something
available, please send the link across)

Just wondering, 'cause then we dont have to learn yet another way of putting
in structured text.

Thanks and best regards,
Vishal Sapre

SHPAML seems popular in bangpypers. :)
Its seems it is just a .py file. Download it from here:

How can we retrieve images from PDFs. I need both images and the text
beneath the image to form a database. I was able to parse text via PDFMiner
but was crippled when it leads to images.

Searching my apt cache for python pdf shows a lot of libraries some of which
claim to be able to manage the entire contents of the PDF file in question.
I have also come across some tool to break a PDF down into HTML + image
files (don't remember it's name anymore) which was free software so I'm sure
it's doable.

Is shutdown a valid command in the new OS?
Atleast it looks like that from the error message.

Try running `shutdown` from the command line and see whether you get
the same error.

Hi,
     Yes 'shutdown' command is working absolutely fine from the command line
at Windows 64 bit,
but I have find something interesting is that :


import os
os.system("cmd")

After running above code at python, then from that command window, I try to
run the 'shutdown ' command,
and its giving the error . I tried to search the "shutdown.exe" file at
C:\WINDOWS\system32 from the same
command window, and it can't locate it, where as I can find it by windows
command line.

try with the full path
assuming shutdown.exe is in c:\windows\system32

os.system("c:\\windows\\system32\\shutdown.exe")

might work.

Or is it c:\windows\system64 ??
I do not have a windows PC to verify this.

My hunch is that python's sys.path does not include the windows system
directories.

os.system(r"shutdown.exe /s") works here, am on a Win7 machine.

sys.path doesn't have anything to do with os.system, it is used only when
searching for modules to load.

Okay, the problem seems to be the fact that you're calling shutdown.exe from
a 32 bit process (I presume you're using the more popular 32 bit version of
python, rather than the native 64 bit one).

Under 64bit windows, any call to a system32/* executable from a 32-bit
process is silently redirected to syswow64\*, which contains 32 bit versions
of (almost) all the executables. So when you call system32\shutdown.exe from
your python process, Windows tries to call syswow64\shutdown.exe.

Problem is, there is *no* 32bit version of shutdown available
(syswow64\shutdown.exe doesn't exist), so your call ends up failing.

tl;dr version - You can't call shutdown.exe on a 64 bit machine from 32 bit
python

Solutions:
1. Use the native 64 bit version of python
2.

Wouldn't it make more sense for you to use the exposed windows API using the
Python win32 module rather than calling an external program via os.popen? I
googled a little and found
http://msdn.microsoft.com/en-us/library/aa376868(VS.85).aspx which should be
callable. I also found
http://mail.python.org/pipermail/python-win32/2008-December/008474.htmlwhich
mentions that setting the appropriate privileges is a pain and
recommends using another module which is linked to.

Use pyPdf. I have worked a bit on PDF structure using pyPdf and written a
library
on top of it for PDF accessibility so I can help you to do this. If you want

help contact me off list.

Unfortunately, the pdf import functionality of Reportlab is not free. It is
called Page Catcher and is part of their paid suit AFAIK.
