Greetings,
On my system I can have several python versions installed because
they install as python2.3, python2.4, etc.

$ which python
/usr/bin/python
$ ls -l /usr/bin/python
... /usr/bin/python -> python2.4

Here, we can see that "python" is just a link to /usr/bin/python2.4
So, I can install python 2.5, and simply change the link so when I
enter "python" at the prompt, it will start python2.5.

$ man ln
ln [OPTION]... [-T] TARGET LINK_NAME   (1st form)

So, after installing python 2.5, change to /usr/bin, remove /usr/bin/python
$ cd /usr/bin
$ rm python

And now make a new link to python2.5 (you may have to be root!):
# ln -s /usr/bin/python2.5 python

If I'm not mistaken, the library files, and so forth are stored in different
directories, so installing a new version, won't corrupt an older version.
..../lib/python2.4/site-packages

See how python 2.4 is in the python2.4 directory?

If, for some reason, you want the other version, just start it with the
absolute pathname:
$ /usr/bin/python2.3

I hope this is helpful? I don't use Mandrake, so I'm unfamiliar with
its package manager, or how to do upgrades for it. The above are
generic *nix commands that should work with any distro.

apt-get and Synaptic rock! =)
