In PyGame for Game Development, I showed you the very basics of PyGame's graphical side. However, creating a game with PyGame requires a bit more. All the concepts described before need to be glued together somehow, and new concepts will need to be introduced in order to create a functional game. In this article, we'll do just that by tackling a working example of PyGame's capabilities—a Python-powered game.

In this paper, an implementation of "Stackless Python" (a Python which does not keep state on the C stack) is presented. Surprisingly, the necessary changes affect just a small number of C modules, and a major rewrite of the C library can be avoided. The key idea in this approach is a paradigm change for the Python code interpreter that is not easy to understand in the first place. Recursive interpreter calls are turned into tail recursion, which allows deferring evaluation by pushing frames to the frame stack, without the C stack involved.
