Would someone with experience in Python please look at the code of this framework and say whether it is good to learn from?

Had a quick look at a few source files in:

http://bazaar.launchpad.net/~pytower-heros/pytower/main/file...

The code looks readable, very well commented and it appears that game objects are split into appropriate classes and modules.

Go for it.
