Subject: [Python Wpg] Prescribed way to run doctest on all modules in many
packages
Message-ID: <1191529904.17262.5.camel@sweidman-laptop>
I was wondering if any doctest experts out there have a "clever" way to
run doctests in all modules in a given set of packages. Currently I'm
doing this:
"""
rundoctest.py: run all doctests in a directory
"""
import doctest
from glob import glob
def _test():
for f in glob('*.py'):
doctest.testfile(f, optionflags=doctest.ELLIPSIS)
if __name__ == '__main__':
_test()
which is terse, but seems clumsy, since I have to have one of these
"rundoctest.py" things in every package. Any suggestions?
Thanks in advance!

I don't know if this info will help. Check out http://freshmeat.net to
find some testing packages. As I recall there is at least one which
shows up there semi-regularly. I can't recall the name (then again I'm
having trouble recalling much lately). I haven't looked at in great
detail but I gather it will perform bruit force checks of all parts of a
program.

Message-ID: <1192048588.18335.14.camel@sweidman-laptop>
Here are the room assignments for PUG through March 2008. We'll have to
book for April, May and June after the spring session courses get
scheduled. It's pretty simple: room 3M58. Third floor, Manitoba Hall, room 58.
Oct 24, 2007: 3M58
Nov 28, 2007: 3M58
Dec 26, 2007: Boxing Day. No meeting, U of W closed
Jan 23, 2008: 3M58
Feb 27, 2008: 3M58
Mar 26, 2008: 3M58
Room 3M58 is a smaller seminar room with rectangular (8 ft) tables and a
wall for a projection screen. Seats about 15 to 20. We can be relocated
if it looks like we're going to have a big crowd.
Regards,
Syd

Subject: [Python Wpg] Testing for Python version
Message-ID: <1192552303.9533.13.camel@sweidman-laptop>
Hi, all!
I'm trying to create doctests that will work on multiple platforms, each
with different versions of Python. OSX includes version 2.3.0, which
doesn't have doctest.ELLIPSIS constant available, so I need to skip
using that constant on OSX. It seems as if the idiom for testing Python
version is sys.version_info[:3] >= (2,4,0):
import sys
import doctest
def _test(verbose)
if sys.version_info[:3] >= (2,4,0):
doctest.testmod(verbose=verbose,optionflags=doctest.ELLIPSIS)
else:
doctest.testmod(verbose=verbose)
Does this seem like the "right" way to test python version?
I can't seem to find any definitive documentation about how to do this.

Hi Syd,
Why not simply check for the feature(s) you need? I have seen lots of python code which takes this approach. For example:
def _test(verbose)
if hasattr(doctest, 'ELLIPSIS'):
doctest.testmod(verbose=verbose,optionflags=doctest.ELLIPSIS)
else:
doctest.testmod(verbose=verbose)

Sorry I won't be able to make it (yet again) this month. A throat
infection this time. As I was mentioning to a couple of people... It's
been one thing after another since spring. A couple of days ago I was
sounding like a cross between Jack Klugman and a Cylon. With everything
else happening right now, I am really wiped out. The doctor says I
should be fine by the end of the week.
With Python related stuff. When I'm feeling better and not watching the
world through a "fish bowl" I plan on writing a short program for door
prize give-aways. The reason is I'll be doing a short presentation for
the MWCS in two weeks (an N64 emulator under OS X) and I have a coupon
for a free bag of chips from Subway. I'd give it to the Python group (or
someone who lives near by) but it would be more effort for someone to
collect it than it would be for them to just buy one. Anyhow, I plan for
multiple prize submissions with one prize per winner. I will post the
code when it's done here. OTOH, if someone already has the code or is
just looking for some practice go ahead and post it.

So...after lurking on this mailing list for the better part of two years (I

figure I should pick up this "Python" thing that everybody's talking about.
Any suggestions for specific online tutorials (or books that are worth the
dollars)? I'm not a new programmer, just new to Python (I've mostly been a
C/Java/php guy). I mean, I can type "python tutorial" into Google as well as
the next guy, but maybe someone here can suggest something that would save
me the digging around for something worthwhile.
Thanks.

The two online tutorials that I found most helpful were:
Think Like a Computer Scientist, Python version:
http://www.ibiblio.org/obp/thinkCSpy/
And although it has not been updated since 2004, Dive Into Python should
also be helpful:
http://www.diveintopython.org/toc/index.html
I've also grown very fond of O'Reilly's Python Cookbook recently, which
provides hundreds of examples of how to solve typical programming
problems in Pythonic ways.
And then, of course, there's Stuart's various introductory talks which
are all excellent.
Hope this helps.

This page about descriptors and the descriptor protocol touches on some
of what Stuart was talking about at the last meeting with respect to
when __getattr__ method is invoked:

I found the document interesting and helpful, as was Stuart's
presentation.

Good resource. I'm aware of property but haven't used it
consistently. Here's a snippet of the old code I presented last week
and a new untested version which uses property instead of __getattr__.
# Old
class Event:
def __str__(self):
return '%2d %6s %s' % (self.EventClass, self.Duration, \
(self.TextData[:30] if self.TextData else ''))
def __getattr__(self, name):
if name is not 'spname':
raise AttributeError
self.spname = e.TextData.split()[0]
return self.spname
# New
class Event(object):
def __str__(self):
return '%2d %6s %s' % (self.EventClass, self.Duration, \
(self.TextData[:30] if self.TextData else ''))
def get_spname(self):
if not hasattr(self, '__spname'):
self.__spname = e.TextData.split()[0]
return self.__spname
def set_spname(self, value):
# needed to make spname a data descriptor
raise AttributeError
spname = property(get_spname, set_spname, None, "Stored procedure name")

Subject: [Python Wpg] remove dup mails
Message-ID: <4728B55C.9060406@pogma.com>
I mentioned at the meeting that fetchmail went mad and downloaded my
mail messages repeatedly leaving me with multiple copies of several
hundred messages. The files were not identical, but only differed in
"Received" headers. This the the python script I came up with (it took a
while, I had to spend a good deal of time reading the docs).
I'm sure that there are better ways to do this, and would not mind a
critique, but this did work.
Thanks,
Peter

This looks great! I can't think of significantly better ways of doing
it. Here are some style suggestions.
Follow PEP 8 (http://www.python.org/dev/peps/pep-0008/) for
indentation, etc. Note that __delitem__ is a special name, intended
to implement dicts, so see how I used it below (untested). Also, file
is one of the objects that follows the new context management
protocol which allows you to use it with "with" a la
http://docs.python.org/whatsnew/pep-343.html and get rid of the try
and both closes. Lastly dict's support the "in" operator.
So here's a slightly different version:
#! /usr/bin/python
from __future__ import with_statement
import os
import sys
import email
import hashlib
dups = {}
for root, dirs, files in os.walk('a'):
for fname in files:
with open(os.path.join(root,fname)) as fobj:
msg = email.message_from_file(fobj)
del msg['Received']
hash = hashlib.md5(msg.as_string()).hexdigest()
if not hash in dups:
dups[hash] = os.path.join(root,fname)
else:
print 'unlink'
# os.unlink(os.path.join(root,fname))

One more thought, not Python-related. Wouldn't msg['Message-id']
reliably replace the hash as a unique handle on the message?

I considered that, but, did not trust that the Message-id was, in fact,
a unique message identifier. I don't know enough about email.

Thank you for the review and pointers.
