Great - pen & paper is what I use as well. No practical technology
that I know of can be as free flowing as pen & paper.

It is very flexible; I can draw flow charts, tables, crude class
diagrams ... and however else I want to model the information that I
need to think over.

For UI design, Blasmiq is pretty good even for us programmers.

Hi Pypers,

I had great Python meet up in June at IIMB and met *Noufal Ibrahim and other
python guys.* *Noufal Ibrahim asked us to spread the word.. Here is message
I have written for our developers (40+)  and I will be sending this to 100s
of my other friends and ask them to forward to many others.  Can you review
the content, tell me if anything I missed out?* or point me where I can get
introduction message with personnel touch :-)


Dear Team,

Indian Python developers community is organizing the Pycon India 2010, a
large Python developers meet-up exclusively about Python language by Python
developers on Sept 25, Sept 26 (Saturday & Sunday) in Bangalore at MS
Ramaiah Institute of Technology, Bangalore. For details visit
http://in.pycon.org/2010/.  There would be various topics presented to
audiences who are from Python beginners to expert developers. The hall would
be full of geeks and nerds talking Python. You can get opportunity to meet
people with different application domains.

If you have experience in Python and interested in presenting paper, you can
submit your proposal here http://in.pycon.org/2010/cfp. Call for proposal is
open till July 31.. You can see my proposal here
http://in.pycon.org/2010/talks/12-Building-High-Performance-websites-using-Python-and-Redis(Awaiting
for review!!!). You can find more talks here..
http://in.pycon.org/2010/talks.

Python has been used with almost all the operating systems, Java
environment, .NET, Embeded and Mobile devices.

Whatever technology you are using or mastered, you should know at least one
nice scripting language like Python or Ruby to solve your own problems. You
can write 10 or 20 lines of code in 5 minutes and it can save you a day or
week (that depends on your manual work complexity). Python would be useful
for writing small throw away scripts to large enterprise applications.  I
strongly recommend you to get participate in the Pycon India meeting.

Thanks & Regards,

Gopalakrishnan

Hi Gopalakrishnan, 

The email is pretty good.

Python is a general purpose programming language. People have some
reduced view of any language which is termed as scripting language,
which is sad and gives on oblique view of the language.

So, use the term 'general purpose programming language' which suits
it better. Also, point to www.python.org for more information in the
email.

Swell email. Thanks! 
I think a little note at the bottom mentioning the twitter account
etc. would be useful. The site has that but putting it in the email is
always nice. 

Thanks again.

Hi
I am new to python and to bangpyers, and I am just starting out my career
with embedded systems and python. Please I may not sure, but wish to add
some comments to this mail.

In last para changing the first few lines to "Whatever technology you are
using or mastered, you will find something in python. And you can save your
work of day or week with few lines of python code with five to ten minutes."
may sounds good I hope.

Thanks

Hi Everybody,

This is my first post here.

What a coincidence. I was just reading David Goodgers Code like a
pythonista: Idiomatic
python<http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html>

<http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html>According
to his website his name is pronounced "like Badger but Good!". So please
remember that when introducing him. He will be a great keynote speaker.

Also I just released an Open Source frame work for App Engine Python, which
you can see here. Eezee MVC <http://code.google.com/p/eezeemvc/>.

Look forward to participating in this forum fruitfully, and hope to meet all
you guys at PyCon India 2010.

Thanks

Hi Manu,
   That's a good suggestion. I'm not familiar with K-mug or the
DEVCON. Do you know some of the people involved there? If so, please
pass on the word about PyCon to them and ask them to spread the word.

Thanks again!

Also, we don't have a "corporate fee". There's just one fee (which Anand
has mentioned above).

Subject: [Inpycon] T-shirt/Logo designs
To: Mailing list for the PyCon India conference <inpycon at python.org>



Hello everyone,
? ? ? ?We need a T-shirt.

? ? ? ?This is going to be the one thing (apart from word of mouth)
that will give us publicity *after* the conference. Therefore, it has to
reappy kick butt. Also, the designer will get to see her designs
wandering around the country for a whole year which is definitely good
publicity.

? ? ? ?A logo and a snappy T-shirt design are two things we need to come
up with. Needless to say, it would be highly preferred if someone from
the community itself came up with a design. If not, we'll have to pay a
professional artist to do it. That's a last resort and I'd rather not
blow cash on it. We had some nice submissions for the Badges and need
some nice ones for the T-shirt.

? ? ? ?A lot of people mailed me with cool badge ideas *after* we
decided on the badges. I'm announcing this now so that people have time
to work on something cool and exhibit it.

? ? ? ?The page to upload your contributions is
http://wiki.python.org/moin/PyConIndia2010/Artwork (I've made sections
for the T-shirt and logo).

? ? ? ?So, get the creative juices flowing and let's see what we can

I have a couple of people I can contact. I'd much prefer that the
community itself came up with designs (similar to what we did for the
logo last year).

Hi Noufal,

I entirely agree with you, nothing like the community coming up with the
design.

I'm not sure what you want to do. What do you mean by the following
terms
 - fetch (as in "fetch the raw data")
 - raw data
 - accept (as in "accept a text file")
 - equivalent (as in "equivalent bits")
 - store (as in "store it in another file")

IF you're looking to make copies, it's simple enough. Just read from one
(source) and write into the other (destination).

yep similar to that .. but i want the complete text or video file in bit
level and if possible store it in a list.
Well i never tried storing such huge amount of data to be stored in a list

If I remember, Python 3.0 gas byte as a data type where you can play with
bytes.
Otherwise you can open file with read and binary mode

 rf = open("README.txt", "rb")
 bytes = f.read(n) # n bytes or simply read() but it returns string
 wf = open("README.txt", "wb")
 wf.write(bytes) #technically string

OR have a look at http://docs.python.org/library/shutil.html which has many
copy utilities which you need..very simple..

Hi all,

           If you want to take part in an Python sprint "officially",
this is the opportunity since PSF has opened up a program
for it.

http://pythonsprints.com/2010/07/8/call-applications-now-open/

The discussions have been going on the PSF mailing list for
a while and it has been officially opened now. Jesse Noller
(of multiprocessing fame) is the co-ordinator of this program.

Message-ID: <201007101018.51165.lawgon@au-kbc.org>

hi

I have a function that runs ok in a fedora 12 machine but crashes in a lenny 
machine. It is an ajax function (I did not write it) so no traceback. The only 
difference between the two machines is that fedora has python 2.6 whereas lenny 
has 2.5 - so can anyone tell me if there is anything python 2.6 specific about 
the code below:

def allaccounts(request):
	filter_params = request.GET.get("head") or None
	filter_qs = Account.objects.filter(head=filter_params).values_list("id", "name")
	edit_url = lambda x: reverse("editaccount", kwargs={"id": x["id"]})
	
	eval_filter_qs = map(lambda x: dict(zip(("id", "text"), x)), list(filter_qs))
	map(lambda x: x.update({"attrs": {"href": edit_url(x), 
									  "remote": True, 
									  "id": unicode(x["id"]),
									  }}), eval_filter_qs)
	serialized_output = json.dumps(eval_filter_qs)
	return HttpResponse(serialized_output, mimetype="application/json")

Suppose you have two nested lists, X and Y. 
A sample element of X is: 
['NM_032291', '67000041', '67000051', 'chr1', '+']

Another sample element of X is:
['NM_001097', '51183080', '51183635', 'chr22', '+']


A sample element of Y is:
['chr1', '67000046']

Another sample element of Y is:
['chrY', '59033300']

The objective is to identify whether the second element of an element of Y (e.g. 67000046) lies between the the second and third elements of an element of X (e.g. 67000041 and 67000051).

Eventually, one should end up with a modified version of Y, let us say modY, which is a filtered version of Y in which the second element of an element of modY is contained within the second and third elements of an element of X.

Any suggestions on how i should be going about implementing this?

Thanking you,
Vikram

I think you can very well use map function

map (function, list1, list2) where in function you can create your desired
list. What map will do is it will call function for each element from list1
and list2 (same indexed) and will do the stuff defined in the function.

Do let me know if i am close to what you want.

List comprehensions are preferred to map and filter functions.In fact, filter is a syntactic sugar to list comprehension.

Subject: [BangPypers] How to run *.py scripts which interfaces with modules
Message-ID: <AANLkTik4Sgq2s2MqWIZ_c-8j7AfWI8YZ4T6VhygtXdP3@mail.gmail.com>

Hi,

I'd like to know how individual python web scripts of a package are
run independently?

For example: http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/annotate/head:/Mailman/Bouncers/BouncerAPI.py

The BouncerAPI.py program when its run, in turn calls another module
syslog (Mailman/Logging/Syslog.py). How can I execute the program
BouncerAPI.py independently for a unit test and avoid "ImportError: No
module named Mailman.Logging.Syslog" errors ?

Currently each *.py file links (calls?) other modules in different
directories. i'd like to be able to give the PATH externally, else the
*.py file throws an error when its run. Its possible to internally
modify each file but that is tedious task for more than 2-3 files. So
how do i give the PATH externally which will run a *.py file sans the
module errors?

TIA,

Hi,

The root directory (where your package starts) should be added to PYTHONPATH
environment variable.
e.g. if your root directory is /home/<username>/projects/mailman
export PYTHONPATH=$PYTHONPATH:/home/<username>/projects/mailman

Once you do that you "cd" in the project directory and execute by saying
python Mailman/Bouncers/BouncerAPI.py <args>

or you can you use "python -m" if you want to run from a working directory
which is not your project directory.

Also ensure that each package directory contains "__init__.py" file so that
python can treat/identify it as a package directory.

You're right in saying list comprehensions are preferred to map and filter -
not just from a readability standpoint but also from a performance
standpoint. (we all hate that .0001 of sec right? - no seriously)

However filter is *not* a syntactic sugar of list comprehension.

>>> l = [1,2,3,4,5,6,7,8]
>>> def foo(a):
...     return [x for x in a if x % 2]
...
>>> def bar(a):
...     return filter(lambda x: x%2, a)
...

The alleged performance gain of list comprehension comes from the fact that
`filter` involve a function call (here= lambda). I'm sure this can be easily
proved using python -m timeit

Then what is syntatic sugar ?
This.

>>> def foo(a):
...    a += 1
...    return a
...
>>> def bar(a):
...    a = a+1
...    return a

Thanks for replying but I am able to execute independent python
programs. So that's not what my earlier query was all about.

Retrying, with another MM?example:
http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/annotate/head:/Mailman/Archiver/Archiver.py,
where the Archiver.py?file will import the following program/ ?modules
to run.

from Mailman import Mailbox
from Mailman import Utils
from Mailman import Site
from Mailman.SafeDict import SafeDict
from Mailman.Logging.Syslog import syslog
from Mailman.i18n import _ ,

This results in the "ImportError" (mentioned earlier).

Besides?"from Mailman import Mailbox"?in turn?refers to email and its
path is: sys.path.append("/home/<$user>/mailman-2.1.10/misc/email-2.58/email/").

So if I set this path inside each of of these *.pyfiles,? using?? ---
sys.path.append("/home/<$user>/mailman-2.1.10/Mailman/")? command,
etc...? <==? I'm able to test-run it. But without the path setting,
the program fails throwing errors.

Editing each *.py file to append it with "sys.path" is a tedious
process. So I'd like to know, whether there exists?a better method to
set the path externally without changing each program file?  I'd like
to execute these programs independently.

Hope that explains my earlier query a bit more.

TIA,

That is what Naresh was trying to explain. If you want to set the path which the 
python interpreter would look at 'outside' the python modules, you can set the 
environment variable PYTHONPATH.

eg: instead of doing a sys.path.append('/home/<$user>/...') do a:

$ export PYTHONPATH="/home/<$user>/...:/some/other/path:..."

...before executing your python script/application.

If you've ever used a Unix based system you'll recognize that the $PYTHONPATH 
variable is similar to the $PATH variable, in that the interpreter (sh or 
python) looks at this variable to find the command/script/module to execute/import.

There is another way to fix this issue -- the .pth file/site.py. More 
information about this issue at:

http://docs.python.org/using/cmdline.html#envvar-PYTHONPATH

OR a "/usr/bin/env PYTHONPATH=$PYTHONPATH:~/extra/path python" as your
interpreter. I generally don't like doing things that linger.

I read from Python 2.6.3 docs that,copied from chm....

" Note that filter(function, iterable) is equivalent to [item for item in iterable if function(item)] if function is not None and [item for item in iterable if item] if function is None."

Since they said *equivalent* ,i thought both transform to same byte code.I missed the point that they are equal *logically*.

See http://docs.python.org/library/functions.html#type

>>> Bar = type('Bar', (object,), dict())
>>> f = Foo(); b = Bar()

Also see http://docs.python.org/library/collections.html#namedtuple-factory-function-for-tuples-with-named-fields

Anyone switched to Python 2.7 yet?

Those are standard error messages (sys.stderr), you can get it like this:

Seems to be working for me:
http://codepad.org/MppnYU9n

I'm taking a wild guess here, you skimmed the docs and saw log_message() but 
didn't realize it is a method of the BaseHTTPRequestHandler class, *not* the 
HTTPServer class. Did I get that right ? can't blame you if I did, the docs are 
arranged in a such a manner that making this mistake is easy :).

Once finalized, we can send mail to all the offline registrants in
Bangalore to inform about the meetup.

Can we have it on 30th or 31st then ?  Personally I prefer
next week-end since I am a bit busy this week-end.

Noufal ?

Suppose you have the following list:

>>> x =[['cat',10],['cat',20],['cat',30],['dog',5],['dog',1],['dog',3]]

My problem is that i wish to obtain the following two dictionaries:
xdictstart = {'cat':10, 'dog':1}
xdictend = {'cat':30, 'dog':5}

Any nice way to do the above? Thanks.

-------
Those interested in the above problem may consider the following code (which does not actually do what i want):

>>> xdictend = dict(x)
>>> xdictend
{'dog': 3, 'cat': 30}

>>> x
[['cat', 10], ['cat', 20], ['cat', 30], ['dog', 5], ['dog', 1], ['dog', 3]]
>>> xdictstart = {}
>>> map(xdictstart.setdefault, *zip(*x))
[10, 10, 10, 5, 5, 5]
>>> xdictstart
{'dog': 5, 'cat': 10}

I suggest that in such cases, avoid the temptation to do something
clever. If it was difficult for you to write the code, it will be even
more difficult to read and understand it.
Unless there is a very good reason, write the simplest, most braindead code.

xdictstart={}
xdictend={}
for item in sorted(x):
  xdictend[item[0]] = item[1]
  if not item[0] in xdictstart
    xdictstart[item[0]] = item[1]

I don't get it, what's the criteria for creating xdictstart and xdictend ? Is 
start the lowest value of element 1 for each element 0 and xdictend the highest ?

If it is:

 >>> x =[['cat',10],['cat',20],['cat',30],['dog',5],['dog',1],['dog',3]]
 >>> d = {}
 >>> for k, v in x:
...     d.setdefault(k, []).append(v)
...
 >>> d
{'dog': [5, 1, 3], 'cat': [10, 20, 30]}
 >>> xstartdict = {}
 >>> xenddict = {}
 >>> for k, v in d.items():
...     xstartdict[k] = min(v)
...     xenddict[k] = max(v)
...
 >>> xstartdict, xenddict
({'dog': 1, 'cat': 10}, {'dog': 5, 'cat': 30})
 >>>

The opposite can be done to obtain the xdictend.This is one way.There might
be some easier way's but i'm not aware it.

Don't know if this is nice, but I might want to solve this problem in
Python like this -

###
from collections import defaultdict

items = [['cat', 10], ['cat', 20], ['cat', 30], ['dog', 5], ['dog',
1], ['dog', 3]]
item_values = defaultdict(list) # this makes the values of this dict
lists by default

starts = {}
ends = {}

for k, v in items:
    item_values[k].append(v)

for k in item_values:
    starts[k] = min(item_values[k])
    ends[k] = max(item_values[k])

print starts, ends
###

Feedback appreciated.

Regards,
BG

Yes. Try this.

>>> x =[['cat',10],['cat',20],['cat',30],['dog',5],['dog',1],['dog',3]]
>>> x.sort()
>>> xdictstart = dict(reversed(x))
>>> xdictend = dict(x)

Never - "filter", "map" etc are implemented as functions so each
call involve a function call in Python which is costly. List comprehensions
are implemented in the language and hence much more optimized.

So if you are aiming to extract maximum juice from your Python
code, prefer native language constructs like comprehensions
as opposed to "outsiders" like map, filter etc. If required, always
prefer the itertools version of these functions such as itertools.imap
etc.

Are you sure that'll work ? Is creating a dict from a sequence guaranteed to be 
executed serially withing the sequence ?

Unless there is a very good reason, write the simplest, most braindead code.



xdictstart={}

xdictend={}

for item in sorted(x):

 xdictend[item[0]] = item[1]

 if not item[0] in xdictstart

  xdictstart[item[0]] = item[1]

How about this :
>>> x
[['cat', 10], ['cat', 20], ['cat', 30], ['dog', 5], ['dog', 1], ['dog', 3]]

Remove duplicates for key pair of dictionary.
>>> keys = list(set(i[0] for i in x))
>>> keys
['dog', 'cat']

Now for every unique keys  make a list containing all the items for that
key.
>>> [sorted([i for i in x if i[0]==k], key=operator.itemgetter(1)) for k in
keys]
[[['dog', 1], ['dog', 3], ['dog', 5]], [['cat', 10], ['cat', 20], ['cat',
30]]]

You can now easily create dictionary.
>>> xdictstart = dict(i[0] for i in [sorted([i for i in x if i[0]==k],
key=operator.itemgetter(1)) for k in keys])
>>> xdictstart
{'dog': 1, 'cat': 10}
>>> xdictend = dict(i[-1] for i in [sorted([i for i in x if i[0]==k],
key=operator.itemgetter(1)) for k in keys])
>>> xdictend
{'dog': 5, 'cat': 30}

The benefit is you can make a complete dictionary if you want, not only
start and end values.

It is nowhere mentioned in Docs IIRC but I have never seen any counter
example.

Yes, it is. Since the list is sorted, the entries are entered into the
dictionary
serially (list is ordered), so hence in normal order we find the larger
value
overwrites the others and in reversed order, the smaller value.

 I cannot think of a solution which is shorter than this.

Out of curiosity I tried benchmarking few of these solutions alongwith 
the one I wrote using itertools.groupby.
My benchmarking did include large data sets and worst case.
Results are the shortest solution (by Anand) was way faster than others. 
After that it was Steve's and mine and Navin was almost the same of the 
last spot.

Which one is most readable? Well I leave that for now.

Anand's solution is the preferred one obviously. Readable and fast.

Actually it is guaranteed.
>From the documentation of "dict":

"The elements of the argument must each also be of one of those kinds,
and each must in turn contain exactly two objects. The first is used
as a key in the new dictionary, and the second as the key?s value. If
a given key is seen more than once, the last value associated with it
is retained in the new dictionary."

Hey BG,

For worst case and dataset in problem your script beats all.
For simple but large data it's Anand's solution just slightly ahead.

Wow.

Below given is solution to a puzzle(
http://projecteuler.net/index.php?section=problems&id=14) in python and c

Python:

import time
startT=time.time()
maxlen=0
longest=0
for i in xrange(1,1000000):
 last=i
 cnt=0
 while(last <> 1):
  cnt=cnt+1
  if(last%2==0):
   last=last/2
  else:
   last=3*last+1
 if(cnt>maxlen):
  maxlen=cnt
  longest=i
print "time taken (sec) : ",time.time()-startT
print maxlen,longest

Python Output:
time taken (sec) :  99.4702298641
524 837799

C:

#include <stdio.h>
int main(int argc, char **argv)
{
int longest = 0;
int maxlen = 0;
int i;
unsigned long last;
for (i = 1; i <= 1000000; i++)
{
 last = i;
 int cnt = 0;
 while (last != 1)
 {
  cnt++;
   if (last % 2 == 0)
    last = last / 2;
  else
    last = 3 * last + 1;
 }
 if (cnt > maxlen)
 {
 maxlen = cnt;
 longest = i;
 }
}
printf("longest: %d (%d)\n", longest, maxlen);
return 0;
}


My doubt is that in C the result comes in 1-2 sec but in python it takes 99
secs.I don't expect python to be as fast as c but i cant understand why it
should be so slow in python.i'm new to python so if there is better way to
do the above prog in python please suggest.

31st is better for me also, bcos i will be in bangalore then. However this
is my first time and i don't know how i could be useful/helpful. Atleast I
can meet you all and see how I could be useful/helpful.

Python is undoubtedly slower than C, more so when you use a naive
algorithm. Here is how I had solved this problem in Python on Jan,
2007 (had to really dig out the code from my archives) -

#!/usr/bin/env python

# Solution for problem #14 at Project Euler
# (http://projecteuler.net/index.php?section=problems&id=14)
# Author: Baishampayan Ghose <b.ghose at gnu.org>

length = 0
max = 0
start = 1

def cycle(x):
    ''' Calculate the max cycle length,
    ensuring that everything is < 1 million
    '''
    i = 1

    while (x != 1):
        if (x % 2 == 0):
            x = x / 2
        else:
            x = 3*x + 1
        i += 1

    return i

for i in xrange(800000, 840000):
    length = cycle(i)
    if length > max:
        max = length
        start = i

print start

###

The above code gets the result in 1.7 seconds on my machine (the C
version takes 0.8 secs). The trick here was to calculate the range
properly, which you can arrive at by using some math.

Note that brute force approaches rarely work with project Euler
problems. There is most certainly some math involved somewhere which
can simplify your solution a lot.

Hope this helps.

Regards,
BG

BTW the problem is known as 3n+1 problem and you can find it in ACM archives
too.

Nice ! Thanks for digging that out Navin ! Anand's solution is really the most 
elegant.

Hi All,

I am collecting information for python related websites and blogs. I am
primarily looking for the sites already offer RSS 1.0/2.0 or ATOM feeds with
clear separation for python related information.

A generic python related info like CPython, IronPython, Jython etc shall be
mentioned here along with top level news site.

Python related information shall be placed here..
http://stacked.in/python

There would be separate sections like like /pythonblogs, /django  and
/djangoblogs shall be added soon. I read some blogs like ben bengret, Ian
Bicking, Coders who says py, Amix, Guido (not in particular order). Do you
read any specific python related blogs? You can visit here for more blog
update from 100s of developer..http://planet.python.org/ I am not sure any
Indian blog..

I could see Baiju blog mentioned in planet python...Do you write about
python regularly? please share the link with me.

the folloeing will work..
>>> x=[['cat',30],['cat',40],['cat',10],['dog',5],['dog',7],['dog',1]]
>>> x= sorted(x)
>>> xdictstart=dict(zip([x[0][0],x[3][0]],[x[0][1],x[3][1]]))
>>> xdictstart
{'dog': 1, 'cat': 10}
And similarly for dictend..

Are you sure that'll work ? Is creating a dict from a sequence guaranteed to be 
executed serially withing the sequence ?

Unless there is a very good reason, write the simplest, most braindead code.



xdictstart={}

xdictend={}

for item in sorted(x):

xdictend[item[0]] = item[1]

if not item[0] in xdictstart

  xdictstart[item[0]] = item[1]

How about this :
>>> x
[['cat', 10], ['cat', 20], ['cat', 30], ['dog', 5], ['dog', 1], ['dog', 3]]

Remove duplicates for key pair of dictionary.
>>> keys = list(set(i[0] for i in x))
>>> keys
['dog', 'cat']

Now for every unique keys  make a list containing all the items for that
key.
>>> [sorted([i for i in x if i[0]==k], key=operator.itemgetter(1)) for k in
keys]
[[['dog', 1], ['dog', 3], ['dog', 5]], [['cat', 10], ['cat', 20], ['cat',
30]]]

You can now easily create dictionary.
>>> xdictstart = dict(i[0] for i in [sorted([i for i in x if i[0]==k],
key=operator.itemgetter(1)) for k in keys])
>>> xdictstart
{'dog': 1, 'cat': 10}
>>> xdictend = dict(i[-1] for i in [sorted([i for i in x if i[0]==k],
key=operator.itemgetter(1)) for k in keys])
>>> xdictend
{'dog': 5, 'cat': 30}

The benefit is you can make a complete dictionary if you want, not only
start and end values.

It is nowhere mentioned in Docs IIRC but I have never seen any counter
example.

Thank you for posting. Please try to trim the message backlog
when replying. In your email, your reply was like 10% and the
long tail made up 90% of the rest. It just adds up to the noise.

What you mentioned here is the exact mechanism of a instantiation of a class
by metaclass.
Here class is `Bar` and MetaClass is `type`

Normally,
clsObj = Class() #l = list(), d = dict() etc


and for instantiaing Class,

Class = Metaclass(Class.__name__, bases, dict)

Few friends and me are planning to attend the pycon 2010, but  accommodation
is a problem.

We have no contacts in Bangalore. Could anyone suggest a place to stay
(hotel/lodge) or give contacts. Our budget is low, ( about 1000 for 4 people

So, is 31st fine with everyone? I will attend but am currently tied up

organising this meetup (venue etc.) and collecting the registration
money of the offline participants? 

Anand C. has a setup to mail the offline registrants with the venue
etc. so that they can attend (not all of them are on BangPypers) so
please let him know as well.

A less readable solution using itertools

#------------
from itertools import *

get_first = lambda x: x[0]
filter_first_and_chain_rest = lambda seq: chain(*(x[1:] for x in seq))

data = [['NM100', 1, 2], ['NM100', 3, 4], ['NM200', 5, 6]]
grouped = groupby(sorted(data), get_first)
print list ([label] + list(filter_first_and_chain_rest(grp)) for label, 
grp in grouped)

This problem begs for the use of collections.defaultdict class.

All the other solutions are ok, but defaultdict is meant to solve
problems like this.

Here is the solution.

>>> import collections
>>> l=[['NM100', 1, 2], ['NM100', 3, 4], ['NM200', 5, 6]]
>>> l2=[[x[0], x[1:]] for x in l]
>>> d = collections.defaultdict(list)
>>> for k, v in l2: d[k].extend(v)
>>> [[k, v] for k,v in d.iteritems()]
[['NM100', [1, 2, 3, 4]], ['NM200', [5, 6]]]

What you want are the elements of the final list.

I didn't notice you want

z = [['NM100',1,2,3,4],['NM200',5,6]]

rather than,

z=  [['NM100', [1, 2, 3, 4]], ['NM200', [5, 6]]]

So replace last line with,

>>> [[k] +  v for k,v in d.iteritems()]
[['NM100', 1, 2, 3, 4], ['NM200', 5, 6]]

Hi Gopalakrishnan Subramani,

I write a blog which is not exclusively on Python, but contains a good
amount of percentage of information/codes and other details on Python and
Google App Engine platform. The URL is http://codecontrol.blogspot.com. You
may visit the blog and add it to the list.

Thanks,

Hi,

I was thinking if we can use Google Moderators (
http://www.google.com/moderator) and google wave to make the talks for PyCon
India more interactive and lively.
If we could come up with a plan of usage of these tools, maybe we can inform
the speakers in advance so they will be more comfortable with it.

Hi Anand,vijay, and others,
we have python 2.4.3 at our workplace and defaultdict is not present in the collections module in this python version.

>>> dir(collections)
['__doc__', '__file__', '__name__', 'deque']
>>> 

Also, could u suggest some way to tackle the following problem:
Given:

l = [['NM100', 1, 3], ['NM100', 7, 10], ['NM200', 13, 16]]

want something like:
 z = [['NM100',[1,2,3,7,8,9,10]],['NM200',[13,14,15,16]]]

I've moved the discussion to the inpycon list since it's more
appropriate there.

"Changed in version 2.5: Added
defaultdict<http://docs.python.org/library/collections.html#collections.defaultdict>
."

So it is not present in Python <=2.4.

Why don't you attempt an approach yourself before asking
for help ? Now that you have already seen some solutions
to the first query, isn't that better ?

Is there no one with a little time to take care of this? It just
involves a few emails/phone calls to the venue and an email to confirm
the date.

Hi All,

This is my first time and I really wish to contribute. I probably can make
the phone calls. If you think I can do it send me the list with instructions
and I will do the phone calls.
Thanks

In the mean while please let me know if this okay will all of you.

And please help me make my first time effort successful. :)
Thanks All

Friends,

Microsoft also provide space for community meet up. PHP meet up happen often
their. Do let me know if you guys need in touch with the concern person. He
told me that he would be happy to provide space for community meet up. You
can take this as alternate to other venue. The address is Microsoft, ground
floor, signature building, EGL, Domlur.

They have all setup ready and 50-60 people easily accommodate. I think wifi
needs permission, rest everything is available for use.

I dont have python 2.4.3 right now to test what I'm going to say, but
behaviour of defaultdict can be simulated (correct me if I'm wrong, again
because of version freeze I'm never over 2.5.1) using dict.setdefault


The way I understand defaultdict is, it never raise a KeyError, instead
assumes the default 'value' of every key as the one that you initialize it
with (here= list)



d = {}

and instead of doing

d[key_doesnt_exist] = my_values

do

d.setdefault(key_doesnt_exist, []).extend(my_values)

# if key doesnt exist, it returns the default (second argument) .. and you
can call methods on it - append, extend .. what have you.


I'm assuming you know this already and hence this rather vague description.
If you want more pointers just ask I can reply in a much more descriptive
way.

yeah you're right. The same question was posted elsewhere. I hope the author

Yes, this approach works if you haven't got collections.defaultdict.

>>> l=[['NM100', 1, 2], ['NM100', 3, 4], ['NM200', 5, 6]]
>>> d={}
>>> l2=[[x[0], x[1:]] for x in l]
>>> for k,v in l2: d.setdefault(k,[]).extend(v)
...
>>> d
{'NM100': [1, 2, 3, 4], 'NM200': [5, 6]}

Hello folks,

Slight change of plans. The builders at our Domlur office want to perform
some electrical maintenance work this weekend. I hope meeting at the
Koramangala office instead at the same time wouldn't be too inconvenient.

Hi all,



Say I have 10 functions in base class and I have inherited it in some
derived class.

But I only want 9 of the base class function to be available in child class.
(and I don?t want to make that one class private)



class x:

    def __init__(self):

        self.a =3

        self.b= 4

    def A(self):

        print (self.a)

    def B(self):

        print (self.b)



class y(x):

    def __init__(self):

        x.__init__(self)

        del (self.A)                                  #This is giving    del
(self.A)

AttributeError: A

Python encourages clear design by not providing facilities to /enforce/ policies 
as part of the language. That's the reason why there are no 
public/protected/private keywords in python. There are only conventions to be 
followed. Here are some possible solutions:

a. Are you sure you got your class hierarchy right ? If one class needs all the 
methods of the other except one, the one with the most commonality should 
probably be the base class. In your case, it would be flipping the hierarchy on 
it' head.

b. If some method is 'special' to a class name it using leading and trailing 
'__' so that users deriving from the class know it is special.

c. This is now going into hacky territory -- if you decide to keep the same 
hierarchy as you have now, assign self.A in class 'y' to None[1] or explicitly 
implement it to raise an AttributeError[2]. The reason you cannot 'del' self.A 
is precisely because of what the error says "AttributeError: y instance has no 
attribute 'A'" -- A is just a 'bound' method to the object, not an attribute of 
the object and AFAICT there is no way to un-bind something off an object.


[1]

class y(x):
     def __init__(self):
         super(y, self).__init__() # btw, use super if possible
         self.A = None

[2]
class y(x):
     def __init__(self):
     ...
     def A(self):
         raise AttributeError("y instance has no attribute A")

hth,

Nitin,
         del can only remove the elements present in the instance dictionary. If you check self.__dict__ then it shows that A is not in the dictionary only 'a' and 'b' exist in the dict that's why it is giving the attribute error.

I didn't get what is meant by hiding?
You can override the function/method of base class in sub class.
In that method, you can modify the behaviour for subclass or 
raise an exception or simply include 'pass'.

Anyway, deleting any property of a class in it's subclasses clearly violates the liksov substitution principle.

You can try obscuring it:

class y(x):
   def __init__(self):
       x.__init__(self)
       self.A = None

Is the venue final then? I've not seen may +1s.

I need to send a mail to offline registrants about the usergroup meeting.

I'm out of city right now and won't be able to make the meeting.

This time it wont possible in Microsoft. I spoke to him and he willing to
help out from next time. They need atleast one week advance notice for meet
up to arrange and for security clearance. Keep MS as alternative from next
time.

Trying to do something like this in Python shows a mistake
in the design of your classes. There are different ways to
do this in Python. Here are a few.

1. Prefix the function with double underscore ('__')
 as steve said in his email.
2. Override the function accessing method using
a decorator and put the logic in the decorator to return
None if a specific function is accessed.
3. Raise NotImplementedError if the calling class
is not the super class.

I have given sample code for (3) here.

class A(object):

    def f1(self):
        print 'Hi'

    def f2(self, x):
        if self.__class__.__name__ != 'A':
            raise NotImplementedError
        print x

class B(A):
    pass

if __name__ == "__main__":
    a=A()
    a.f1()
    a.f2(10)

    b=B()
    b.f1()
    # Will raise exception
    b.f2(20)


However it is better to look at why you need it than
to use any of these approaches and correct that requirement.
Normally in Python, you never need a requirement like this.

HTH.

I would find a talk on the lines of "Data Structures and Algorithms using
Python" interesting. No body has submitted it so far:
http://in.pycon.org/2010/talks

I am sure there are people on this list that have expertise to do that. I am
just planting an idea and encouraging someone to do that!

The talk could discuss about all aspects of Trees, linked lists, O(n) etc,
as can be reviewed quickly in pseudo code using this book:

We had it last year. See if you or any of your friends would like to do it.
Feel free to use the same material.

Senthil gave a talk last year on 'DS and Algorithms'. Also my talk covers a
particular Data Structure. It is not general but it is related. I even
tagged it 'data structures, newbie'

Very interesting indeed that we had it last year. Perhaps you should do it
again this year. At least I'd love it, if you did!

As much as I would have loved to, my bandwidth is already taken off for
another talk I submitted, which is specifically in my area of expertise.

Nothing in particular to mention. There were quite a few students. We
collected 5 registration fees (Rs. 250 each). I picked up the ZeOmega
cheque. I'll endorse it and drop it at an ATM tomorrow.

I echo the same sentiments as Anand and Steve. If your class inherits from
something, its assumed the child class is of the same `kind` as the parent.

What you're asking sounds like this,

I have a `Vehicle` class which can `drive()`, now I wanna subclass `Car`,
but my `Car` doesnt implement `drive()` method.


Having said that, I'll add another method to restrict access to this
odd-function using __getattribute__.

What is __getattribute__ ?
  Whenever you do access an attribute, be it for a function or an attribute
(like obj.foo() or obj.value), obj.__getattribute__ is called. Things are
really a little more involved than the simple explanation I wrote, but for
this case you just need to know that much.


class Parent(object):
    def childShouldntCallMe(self):
       doParentStuff()


class Child(Parent):

    def __getattribute__(self, name):
         if name == "childShouldntCallMe":
             raise RestrictedAccessError # This could be a more polite
NotImplementedError
         else:
             return super(Child, self).__getattribute__(name)

To add to what Sibtey already finely explained,

The only valid use case of del/ __del__ happens to be cleaning up the
namespace if you're writing a module. Every other use case of del/__del__
might or might not work.

I recommend sending mails to the whole group if your mail is a followup to
the original problem. The purpose is 2 fold,

1. You'll get more eyeballs -> more quality responses.
2. We can document it more formally so that someone later on can browse mail
archives.

And what happens in a Hacksession?

Subject: [BangPypers] how to handle attribute access
Message-ID: <AANLkTimbU7Qnkvhc4awtrd28zfp2kF09g-FY07NVdn=O@mail.gmail.com>

Hi,

I am working on automating some application. In one window say i have two
ComboBox, but that window have scroll bar. Only one combo Box is visible at
one time.

I have functions to handle scroll of window.

What i want is that how to handle attributes so that one i want to set some
value in the combobox which is not visible, then first that scroll function
is called then the comboBox will do what ever is required.

I will try to explain using one example.

class window:
      def __init__(self):
           self.CB1 = cbObject                    #CB1 is one combobox
object (to do different task on Combo Box)
                                                            #this is visible
once scroll bar on top
           self.CB2 = cbObject                    #CB1 is 2nd combobox
object (to do different task on Combo Box)
                                                            #this is visible
once scroll bar on bottom

    def scroll Up(self):
           ......................
    def scrollBottom(self):
           ......................

    #these above two functions can be used to scroll up and down.

use:

w=window()
w.CB1.Select(val)

w.CB2.Select(val)

Now to set value in wnd comboBox in need to scroll down first. This thing i
want to handle in class. Can i use metaclass (i dont know much about this)
or __getattr__ for the same.

point to note:
CB1 or CB2 are objects not functions. So i don't know if I can over load
that to achieve the purpose.

Thanks
Nitin K

What I meant was that it would be really nice to work on something towards
the end of the whole event or the end of each day.

Maybe a person who might be giving a talk about an open source project of
his could sit around with a few others who are also interested and work on
it.

Another thought that crossed my mind would be to host a sprint towards the
end of the day; Pycon sponsors sprints for contributions on porting,
documentation, bug fixes and much more.

I was wondering if there were plans to have similar sessions during/after
the event.

PSF has opened up a program for organizing and sponsoring
"sprints" related to Python language in an official manner
with the blessings of PSF.

I will try to go on stage and give a few words regarding
this initiative and a few plans on how to take advantage
of this from our side, during the conference. This is not
a "talk" but would be something close to the end of the
conference on day 2.

You can read more about this at http://pythonsprints.com/ .

Is there anyway a sprint could be hosted during the conference?

There is a lot of manpower in a conference such as Pycon-India and a lot
could be achieved in a little time by hosting such a sprint. At the very
least, it'll turn out to be a chance to kickstart one's contribution to
Python.

Also a typo in my earlier mail. Its PSF thats sponsoring the talks, not
Pycon.
