Why don't you compile using python -OO and distribute only .pyo code?

We (CCP) are certainly compiling python without docstrings for our embedded platforms (that include the PS3) Anyone using python as en engine to be used by programs and not users will appreciate the deletion of unneeded memory. K

After a bit of digging, I found the following discussions: http://mail.python.org/pipermail/python-dev/2001-November/018444.html http://mail.python.org/pipermail/python-dev/2002-January/019392.html http://bugs.python.org/issue505375 Another reason for accepting the patch seemed to be that it introduced the PyDOCSTR() macros, which were viewed as helpful for other reasons (some people talked about localizing docstrings). I would point out that if 200 KB is really a big win for someone, then Python (and especially Python 3) is probably not the best language for them. It is also ironic how the executable size went up since then (from 0.6 to more than 1.5 MB) :-) 200K can make a difference. It does on the QNX platform, for example, where there is no virtual memory. It would be nice to reduce that executable size, too....but I'm not volunteering to try (at least not yet) :) --David
