I think it's important not to urge legacy technologies for the sake of other
individuals' not complying, for example the py2exe authors. There will
always be such issues during upgrade paths, but urging others to wait,
simply reduces the pressure to make such things move forward.
I just can't imagine telling someone not to bother learning 3.0 because they
might not require those concepts, especially since 3.0 involves some nice
improvements in making python a more object oriented and further robust
language.
Also, I really don't think that py2exe is quote beginner stuff unquote, in
that distribution seems to be the main name of the game for that one, and
that comes far after the beginning to learn how to program stage.
I absolutely urge folks, regardless of platform, if starting out with python
to learn 3.0.
Just a humble opinion.
Take care,
Sina

I guess that is for folks who still live their life in the Microsoft world.
I have started drifting slowly away from that world for the first time so I
will bow to your advice if I run python in windows I will make sure to stay
with 2.5 for the time.

Python 2.6 is compiled with Microsoft Visual C++ 2008, whereas 2.5 is
compiled with 2003. This results in some incompatibilities with modules
that are not pure Python. py2exe, for example, does not work well with
2.6. I'm on that list, and 2.6 has been a nightmare for folks.
