Hello,

The PyATOM team is proud to announce the initial release of PyATOM.

About PyATOM:

Short for Automated Testing on Macintosh, PyATOM is the first Python
library to fully enable GUI testing of Macintosh applications via the
Apple Accessibility API. This library was created out of desperation.
Existing tools such as using appscript to send messages to
accessibility objects are painful to write and slow to use. PyATOM has
direct access to the API. It's fast and easy to use to write tests.

Changes in this release:

It's the first public release, so none yet!

Special thanks:
The VMware Fusion automation team
Nagappan Alagappan and the LDTP team

Documentation is still a work in progress. Read the README on the
Github page for an introduction to PyATOM.

Just use map(int, x).

- map is functional construct.

- For loop and list comprehension is procedural construct.

In this case functional construct is lot more concise.

map() calls the function across all elements in an iterable, and since strings are iterable in Python, the above actually calls map() on each item in your list. What you want is map(int, x) :-)

Use one of list comprehension or map, not both:

[int(i) for i in x]

or

map(int, x)

should do what you want.

you want either
>>> x = ['1','33','44']
>>> map(int,x)    # map applies the int function agains a list
[1, 33, 44]
>>> [int(i) for i in x]   # or do it explicity yourself with list comprehension
[1, 33, 44]

That's actually a map() call inside a list comprehension. Either a bare map() call or a list comprehension without the map() call will do what you want. 


E.g.,
>>> T2 = map(lambda i: int(i), x)

or 


>>> T2 = [int(i) for i in x]

Others may have gotten there first, but at least I added the completely gratuitous lambda!

Simply do

[int(n) for n in x]

Good Afternoon!

 

I hope you had a great weekend! I wanted to share with you a super hot new
opportunity! My client in San Jose is looking for a C/C++ Python programmer
to help develop specialized services on a new handheld device. Very similar
to an iPad/tablet. They need assistance in the development of location-aware
applications for a mobile platform(Android/iOS)- So if you have done this
before this is a BIG PLUS! They are looking for a minimum 3 year experience
with Python. You would work with a small team to implement this new
functionality as well as review and re-factor code and develop unit tests.
This is a 3 month contact, with potential to extend longer. I have a similar
position, which Python experience is a plus, which is more geared towards a
Graphics Programmer (5 years of C experience is required). I am happy to
give more information for either, so if this is you, or anyone you know
please do not hesitate to reach out! I do appreciate your time!

 

Have a wonderful evening!

Hello,

I have a simple question:
is there an equivalent to <?php  ... ?> for mixing Python and HTML ?

For example something like this:

<body>
  <?python
      if user == 1:?>
  <h1>Welcome admin</h1>
  <?python
      else:?>
  <h1>Welcome</h1>
</body>

Basically something similar in behavior to PHP but for Python ;)

Thanks,

David

Or Jinja2. (although I'm a Mako user).

All of those tools are called templating engines.

you probably should first look at web frameworks, go to
http://wiki.python.org/moin/WebFrameworks or do a google search.  This
url mentions Pylons which is now Pyramid and pretty cool, I have
worked with web2py and it is an easy start, does a lot for you, some
magically, but still cool.

Most of the frameworks let you choose the templeting language, some
which are very pythonic some lean more toward html side. All those
mentioned in prior responses are Fine and will do what you are asking
for.  But you have to have a way to deliver the resultant html, and
writing your own cgi though instructive isn't the fastest way to get
to serving web pages.

Thanks for the quick responses.
Mako seems to be something that could work for me.

Talking about the suggestion of looking into Web Frameworks, I used
Drupal so far but I am not satisfied with the performance and the
overhead of the data structure (even with memcache etc...), so I'm
basically planning to rewrite my website from scratch in a lightweight
way (from SQL point of view in particular, but also memcache etc...).

I don't know enough details about other frameworks but my concerns,
acquired with Drupal, are they might try to satisfy a wide audience
and often at the expense of tight SQL queries. One more concern is the
learning curve, took me one month to understand Drupal, it's a lot of
time and yet there are still a lot of grey areas for me.

So if there's a framework that's compact and fast I would be tempted
to get a look into it, but time is short, I really only have 2 weeks
to rewrite entirely my website which, by the way, is:
http://codercharts.com

Any suggestions are welcome and thanks again for the pointers ;)

I too have been playing around with web frameworks and 
applications.  I've decided to use Pyramid.  Other frameworks 
constrained me into doing things their way, bound me to using a 
specific data source, or lacked sufficient documentation and support.

Pyramid does not get in your way.  It provides only what you 
need and does not constrain you in regards to data sources, 
template engines, URL traversal versus routes, and so on.

I worked through the Pyramid Quick Tutorial in under an hour.
http://docs.pylonsproject.org/docs/pyramid_quick_tutorial.html

Documentation:
http://docs.pylonsproject.org/docs/pyramid.html

Support is available on mailing lists and IRC.  I attended the 
Pylons Project Mini Conference and code sprint last week, and 
met some of the core members of the project.  Just being in the 
same room made me smarter.  These guys and dozens others hang 
out in IRC #pyramid and #pylons.
http://groups.google.com/group/pylons-devel
http://www.meetup.com/sfbay-pylons-proj/events/17306893/
irc://freenode.net#pyramid
irc://freenode.net#pylons

Here is some history.  Pyramid is part of the Pylons Project.
http://pylonsproject.org/about/pylons

Pyramid's core is repoze.bfg with some modifications.
http://pylonsproject.org/projects/pyramid/about

Flask is another lightweight framework.
http://flask.pocoo.org/

Plone is more of a CMS than a framework, but I know that folks 
develop applications in it.  Django has a huge ecosystem around 
it.  At PyCon, many folks said of web2py (except the author), 
"Just don't."

There is also the Pythonic webpy (http://webpy.org/) which includes its own templating language.  I've done a couple of small projects with webpy and would like to know what people who have used it in anger have to say.

Your four event diagram misses 2 of the 15 possible intersections
(yellow + green and red + blue).

This becomes an increasingly difficult topology problem as you add
circles (you need to deal with (2^n)-1 intersections each time).  A
related problem is that as soon as you have more than two circles,
you can not in general make the intersection areas proportional to 
the size of the corresponding set intersection.

An alternate graphic that is useful at high n is a clustered heatmap:

1) Generate a matrix where each column, j, is one of your circles and
    each row, i, an element, with cell ij = 1 if i is a member of j, 0 otherwise.

2) Apply a clustering algorithm to group the rows by related intersections.

PyCluster is a good place to start with clustering algorithms:
http://bonsai.hgc.jp/~mdehoon/software/cluster/

JavaTreeView is a nice visualization tool based on PyCluster's output format:

Tenantry.Net is aimed to support the interactions of tenants (plus
roommates,) and their landlords. The business case is golden; the design,
elegant; and the systems for collaborative development are already up and
running... unfortunately, I'm not a gifted developer.

Prospects both technical and commercial are huge, and the project would love
nothing more than be nurtured by a few talented Pythonistas to
collaboratively design & build the system within the bay area.

If you're interested in learning more about this exciting project, please
don't hesitate to call or email myself to schedule a meet.

Cheers!

Sincerely,
John Sphar

Subject: [Baypiggies] Audio Video Recording of upcoming session
Message-ID: <BANLkTi=4TuC8B0LukCa4JKDwoFh9bVfmOQ@mail.gmail.com>

Hi All -

I recently received an offer to record the May 26th session that I
have been asked to pass to the group. Marakana is an open source
training group for whom I'm going to be doing some teaching. One of
the things they do is record User Group sessions that might be of
interest to the public. You can see examples of their videos at
http://marakana.com/techtv/index.html

Marakana has asked if it would be OK to record the presentation on May
26th. They would bring their own audio and video equipment, record the
presenter and then edit the recording to put the slides in the video
if available. They would post the video to their TechTV channel and
their Youtube channel and would credit Baypiggies and include a link
to our website in the video. You can see some examples of other UG
videos on their TechTV channel.

We used to have all the sessions recorded thanks to Google. Since
we've changed locations we've had to fall back on volunteer equipment
and labor and it's been much more hit and miss - I don't think we've
had a session recorded for a year or so. I'm biased since I'm going to
work with Marakana but do think that any additional exposure we can
gain would be good for Baypiggies. If you've got an opinion please
reply with a vote (+1/-1).

-regards
Simeon Franklin

I've been trying to make use of this module (pyexiv2) but have discovered
that the syntax described in the tutorial
http://tilloy.net/dev/pyexiv2/doc/release-0.2.0/tutorial.html
is very different to the one that comes with my Ubuntu 10.4 system
/usr/lib/pymodules/python2.6/pyexiv2.pyc

I've poked around using Google but can't find any other tutorial that
matches my system.

If anyone can point me in a useful direction, it would be greatly
appreciated.

Hi Alex,

Have you read the source yet?  It looks like it is nicely documented
with docstrings:
>>> import pyexiv2
>>> help(pyexiv2)


I also have some very simple examples of getting and setting image
file metadata in my weather station project.  Here's a link to it on
bitbucket:

http://bit.ly/kwyqo6

Good luck,

Eric.

Good Morning and Happy Friday!

 

I wanted to pass along a great contract opportunity in San Jose with a
growing company seeking assistance with a new product! I would greatly
appreciate any referrals if you are not available, no one knows better
references than yourself!

 

They are for a C/C++ Python programmer to help develop specialized services
on a new handheld device. Very similar to an iPad/tablet. They need
assistance in the development of location-aware applications for a mobile
platform(Android/iOS)- So if you have done this before this is a BIG PLUS!
It is being developed on an Android Linux Kernel platform. You would work
with a small team to implement this new functionality as well as review and
re-factor code and develop unit tests. 

 

Experience and qualifications:

. 3+ years Python experience

. Linux experience (e.g. shell, gcc, ARM)

. Excellent written and verbal communication skills

. Development of location-aware applications for a mobile platform is a big
plus

 

I have a similar position, which Python experience is a plus, which is more
geared towards a Graphics Programmer (5 years of C experience is required). 

 

Experience and qualifications:

. 5+ years C experience (esp. raster graphics using SIMD instruction sets)

. Linux experience (e.g. shell, gcc, ARM)

.Experience of using inline Assembly in C is highly desired

. Excellent written and verbal communication skills

. Knowledge of Python is a plus

 

I am happy to give more information for either, so if this is you, or anyone
you know please do not hesitate to reach out!

Subject: [Baypiggies] Looking for beta testers for Django Platform as a
	Service
Message-ID: <BANLkTi=0-mAo7EWUqTkTSQxARguiVV6zFw@mail.gmail.com>

Hi everyone,
 As I mentioned at the last meeting, I'm looking for people to help beta
test my company's Django Platform as a Service (cloud hosting platform).
We'd love to have your feedback on what you think of our service and what
features you would like to see. If you are interested, please send me an
email or sign up via our website at http://www.genforma.com.

 It seems like there is a lot of interest these days in platform as a
service, so here's what is unique about what we are doing:

   - The underlying platform, Engage, will be released (in June) as open
   source software. You can use it to deploy on your own servers and extend it
   for your specific needs. We have some of our software up today at github:
   http://github.com/genforma. Engage is like a integrated combination of
   Puppet + Fabric + Apt and is written in Python.
   - We support automation of your dev-test-production workflow through an
   application packaging tool and atomic upgrades (including schema
   migrations).
   - Each application instance is deployed in its own Virtual Private
   Server(s). This makes it easy for us to support standard application
   components without having to modify them to work in a multi-tenancy mode.
   You also get more options in what you can install (today, any code that can
   be installed via pip).
   - We'll have support for many standard components including databases
   (MySQL, PostgreSQL, and SQLLite), no-sql data stores (Redis, MongoDB),
   caches (memcached or varnish), and applications (Django-CMS and Satchmo). We
   plan to support other application frameworks in the future as well (e.g.
   Pyramid and Flask).

I'm looking forward to hearing from anyone interested in testing our stuff
and giving feedback.

Thanks!
 - Jeff Fischer

I am unsure how I should package or structure a project with both a C
and a Python component.  If it were only C I would use the GNU
autotools; if it were only Python I would use distutils.

The C component is a program, not just a Python extension module.

For UpLib, a mix of Python and Java and C intended for both Unix and
Windows, I used autotools and Makefiles, and I'd do that again.  You can
still access data from the distutils libraries to use in the configure
scripts and Makefiles, e.g.

  platlib=[`$PYTHON -c "import distutils.sysconfig as sc; print sc.get_python_lib(plat_specific=True, prefix='${UPLIB_HOME}')"`]

	PyATOM- for July 2011
Message-ID: <BANLkTi=RTkjHBvwt4L=+De4AVEyRXjMjUA@mail.gmail.com>

We have a person who wants to give a presentation on PyATOM.
I'm thinking about scheduling him for July 2011.
I don't believe we have anyone schedule for June 2011 yet.

Reply with +1 for yes, or -1 if not.

About PyATOM:
Short for Automated Testing on Macintosh, PyATOM is the first Python
library to fully enable GUI testing of Macintosh applications via the
Apple Accessibility API. This library was created out of desperation.
Existing tools such as using appscript to send messages to
accessibility objects are painful to write and slow to use. PyATOM has
direct access to the API. It's fast and easy to use to write tests.

Special thanks:
The VMware Fusion automation team
Nagappan Alagappan and the LDTP team

Documentation is still a work in progress. Read the README on the
Github page for an introduction to PyATOM.

I wish to read a large data file (file size is around 1.8 MB) and manipulate
the data in this file. Just reading and writing the first 500 lines of this
file is causing a problem. I wrote:

count = 0
for i in fin.readlines():
    print i
    count += 1

        break

and got this error msg:

Just don't use readlines. Instead, if you're reading line-by-line, use the
file object as iterable:

for line in fin:
  ...

You can dress this up a little with something like

import itertools

with open('gene-GS0001') as fin:
   for line in itertools.islice(fin, 500):
     print line

Note that this assumes the datafile is a line-bound file. Otherwise, you
should look at, e.g., using the read() method directly:

chunk = fin.read(512)
...

you can try:

for i in fin:
    ...

This should avoid loading the whole file in memory with .readlines().

Thanks to all for their responses. A correction: my data file is 1.8 GB and
not 1.8 MB as Simeon pointed out.

You don't need the readlines call - the file object itself supports
iteration over lines; readlines() is there is you specifically want to
create a list containing all the lines in the file. Try it with

for i in fin:

instead of

for i in fin.readlines():

and see... Were you mistaken above and is the filesize 1.8 GB instead
of MB? You shouldn't be having memory errors with 1.8MB given a normal
environment. If you are working with multi-gigabyte files, however,
you should read David Beazley's awesome Generator Tricks paper
(http://www.dabeaz.com/generators-uk/). I re-read it on a regular
basis and always pick up something new...

For those using gmail, you can activate the reply button to be "reply

If your data is actually a tsv (tab-separated value format), you should be
using the csv module for actually iterating over lines in it.  Just set the
delimiter to '\t' and look at the docs at
http://docs.python.org/library/csv.html

You should also generally use the "with" syntax when dealing with files
since it handles closing the file object for you (probably not an issue when
you're just reading from a single file, but best practices nonetheless).
 Here's how I would deal with your situation:

import csv

with open('gene-GS00471-DNA_B01_1101_37-ASM.tsv', 'r') as f:
    r = csv.reader(f, delimiter='\t')
    for row in r:
        # row is a list of strings that correspond to the columns in your
file
        do_stuff_with_the_row(row)
# your file object f is now closed

Best wishes,
Lucas Wiman

It's also extremely surprising to me that reading a 1.8MB file is causing a
memory error.  That's actually not a particularly large file, and if it is
causing a memory error, there must be something wrong with the your Python
configuration or build.

Lucas

Subject: [Baypiggies] Egnyte: still hiring
Message-ID: <20110518000918.GA5541@panix.com>

Howdy,

I figured I'd try a more narrative approach this time around.  We're
looking to hire two or three competent Python programmers.  We're looking
for people who can handle server, client, and web programming.  Although
our approach is to hire flexible people who are good at solving problems,
there are some specific skills we're looking for:

* Algorithms/scaling
* Windows
* Virtual machines and file systems (requires some C programming)

I've been working here for almost two years, and I think I have a great
job.  I do lots of different things, I'm rarely bored.  We don't require
degrees, we're more interested in what you can do (I don't have a degree,
either).

For more info, see
http://www.egnyte.com/corp/jobs.html

Feel free to send your resume either directly to me or to jobs at egnyte.com
(if the latter, be sure to mention BayPIGgies).

Looking back over the years, after I learned Python I realized that I
never really had enjoyed programming before.

I should ping the list on that front as well: my main client is Energy
Solutions based out of Oakland. We are really trying to increase our
developer talent right now. See
http://energy-solution.com/index.php/careers/ for the list of openings
but we currently are trying to hire full-time Senior, Middle, and
Junior Devs, we have a project manager spot open and we're looking for
a technical writer as well. ES has been a great company for me to work
with personally and the software side of things (ignore the .php in
the url above) is almost all Python. I'd be happy to personally
introduce any interested parties - especially since they're offering a
bonus for referrals right now!

If you're interested please respond to me directly - I be happy to
fill in some details and point you in the right direction for an
interview.

-best regards
Simeon Franklin

And, as with Aahz and Simeon, my company (mobile spinach) is also hiring. We're trying to find talented software engineers .... I inherited my job and that of another person. And, I'd LOVE to find someone who would work very close with me on projects. We are the backend team that supports the JQuery mobile front end. We do fun things with south, piston, and Django.

I really like the personalities in the team :). We just need one more so I can go home at night :)

Let me know if you're interested...

Glen

I guess I'll put my hand in the air too.

the Consoles group (the group I work in) at Avid Technologies (www.avid.com) is also hiring. We are looking for intermediate and advanced C++ engineers. We use python extensively for automated test and build tools. Windows and/or Mac GUI chops would be bonus. There isn't a formal req written yet but ping me if you have any questions and/or if you'd like to submit a resume.

thanks,
nate

Message-ID: <4DD6FF4A.2020004@cellbiosciences.com>

Cell Biosciences is also hiring.

We are looking for a programmer to work on the software for a
Linux-based scientific imaging system. Our software is written almost
entirely in Python, with Django and JavaScript+jquery used for the user
interface. We are in the process of adding more image processing
capabilities, and a more interactive user interface.

It is a 5 month contract position.

Contact me if you're interested.

Message-ID: <BANLkTinpJ92XqWjQe2CzOO5JQwp1pvTrmg@mail.gmail.com>

Hi everyone,
 I put the slides from my Newbie Nugget about mix-ins up on my blog
at: http://blog.genforma.com/2011/05/27/talk-on-python-mix-in-classes/

 As a bonus, I added a class decorator for checking that a mix-in
class is composed with any required methods. It is described in my
revised slides. I also put a recipe for the decorator up at:
http://code.activestate.com/recipes/577725-class-decorator-to-check-that-methods

 Enjoy!

Hi all,

Just letting you know that the video from Jeff Fischer's newbie nugget 
talk on Implementing Mix-ins in Python is now online: http://mrkn.co/f/345

Coming soon is the video for Alan DuBoff's presentation on Writing 
Titanium Desktop Applications with Python. I'll shoot another email to 
the list later this week when it's up.

Cheers!!
