Python PowerPak is a Python interface to the PowerPak Game SDK, including the PowerDraw, PowerInput, PowerSound, PowerMedia and Power3D.
This library was originally written with the intent of doing rapid game prototyping in Python. SDL itself being too low-level, I chose the higher level PowerPak library. The bindings are done with very straighforward SWIG wrappers and therefore should be easily extensible. However, the bindings is not under active development as I moved first to Guile-SDL then Gauche-SDL. If you are serious about game development in Python you should definitely consider Pygame.
