2 versions of python on 1 machine

[flupke]

I searched with Google and on this newsgroups and i didn't find any info 
regarding this. If there is more info, please redirect me to that info.

I have version 2.3.4 and 2.4 installed on windows and i thought that by 
switching the PYTHONPATH parameter to the dir of the 2.4 version that 
that would make python 2.4 active.

However when i envoke python from the commandline, it still runs 2.3.4
Is it possible to have 2 versions installed and switching versions when
you need to?
How can i do that?
Thanks,
Benedict
