Is it possible to run two versions of Python side by side?

I studied Python for several weeks, and although I have successfully developed applications for the Google App Engine with Python 2.6.5, this requires Python 2.5.

Keeping in mind compatibility issues when loading applications (this is a situation that I would prefer to avoid when learning Python), I wonder if it is possible to have 2.5 and 2.6.5 installed on the same computer. Ideally, I would like to use 2.6.5 by default and configure GAE to use 2.5.
