The department's computer has Python 2.4 and on my home computer (really my dad's computer) I installed Python 2.5.
Is it possible to have Python 2.4 and Python 2.5 on the same computer?

I have done it on one of my machines at work, but with Windows you end up with some problems with file-type associations. You also might have to write a batch file to run DrPython with the correct version of Python. Some IDEs (I think its PyPE) allow you to designate the version of Python you want to use.

Once PyGame has its version for Python25 out, I can stop using Python24.
