python-dev Summary for 2004-11-16 through 2004-11-30
This is a summary of traffic on the `python-dev mailing list`_ from November 
16, 2004 through November 30, 2004.  It is intended to inform the wider Python 
community of on-going developments on the list.  To comment on anything 
mentioned here, just post to `comp.lang.python`_ (or email 
python-list at which is a gateway to the newsgroup) with a subject line 
mentioning what you are discussing. All python-dev members are interested in 
seeing ideas discussed by the community, so don't hesitate to take a stance on 
something.  And if all of this really interests you then get involved and join 

This is the fifty-third summary written by Brett Cannon (Another quarter begins).

To contact me, please send email to brett at ; I do not have the 
time to keep up on comp.lang.python and thus do not always catch follow-ups 
posted there.

All summaries are archived at .

Please note that this summary is written using reStructuredText_ which can be 
found at .  Any unfamiliar punctuation is 
probably markup for reST_ (otherwise it is probably regular expression syntax 
or a typo =); you can safely ignore it, although I suggest learning reST; it's 
simple and is accepted for `PEP markup`_ and gives some perks for the HTML 
output.  Also, because of the wonders of programs that like to reformat text, I 
cannot guarantee you will be able to run the text version of this summary 
through Docutils_ as-is unless it is from the `original text file`_.

.. _PEP Markup:

The in-development version of the documentation for Python can be found at and should be used when looking up any
documentation on new code; otherwise use the current documentation as found at .  PEPs (Python Enhancement Proposals) are located at .  To view files in the Python CVS online, go to .  Reported bugs and 
suggested patches can be found at the SourceForge_ project page.

The `Python Software Foundation`_ is the non-profit organization that holds the 
intellectual property for Python.  It also tries to forward the development and 
use of Python.  But the PSF_ cannot do this without donations.  You can make a 
donation at .  Every penny helps so even a 
small donation (you can donate through PayPal or by check) helps.

Summary Announcements
PyCon_ is coming up!  Being held March 23-25 in Washington, DC, registration is 
now open at for credit card 
users (you can pay by check as well; see the general info page for the conference).

.. _PyCon:

Would you like the source with your function?
Would you like all functions and classes to contain a __pycode__ attribute that 
contains a string of the code used to compile that code object?  Well, that 
very idea was proposed.  You would use a command-line switch to turn on the 
feature in order to remove the memory and any performance overhead for the 
default case of not needing this feature.

Some might ask why this is needed when inspect.getsource and its ilk exist. 
The perk is that __pycode__ would always exist while inspect.getsource is a 
best attempt but cannot guarantee it will have the source.

Beyond a suggested name change to __source__, various people have suggested 
very different uses.  Some see it as a convenient way to save interpreter work 
easily and thus not lose any nice code snippet developed interactively.  Others 
see a more programmatic use (such as AOP "advice" injection).  Both are rather 
different and led to the thread ending on the suggestion that a PEP be written 
that specifies what the intended use-case to make sure that need is properly met.

Contributing threads:
   - `__pycode__ extension 

Skipped Threads
- PEP 310 Status
- python 2.3.5 release?
       look for 2.3.5 possibly in January
- Current CVS, Cygwin and "make test"
- syntactic shortcut - unpack to variably sizedlist
       mostly discussed `last summary`_
- Python 2.4, MS .NET 1.1 and distutils
- Trouble installing 2.4
- Looking for authoritative documentation on packages, import & ihooks
       no docs exist, but feel free to write some!  =)
- String literal concatenation & docstrings
       literal string concatenation only works if the newline separating the 
strings is not significant to the parser
- print "%X" % id(object()) not so nice
       does 'id' need to return only a positive?  No, but it would be nice.
- Bug in PyLocale_strcoll
- Multilib strikes back
- File encodings
       file.write does not work with Unicode strings; have to decode them to 
ASCII on your own
