The convention (more used among Unix variants but I guess the same
thing applies to Windows if you're setting the system path) is that
running "python" from the command line will give you the most recently
installed one. If you want to specify a version, it would be
"python24" or "python25". Each version of Python is installed in it's
own directory and maintains its own path so there aren't any problems
with stdlib conflicts.

As far as Windows file associations go, I suppose the most recent
install would dominate though you could always reset the associations
