Python Programming/Extending with Pyrex
Pyrex is a compiler of Python-like source code to the C language, intended to make it relatively easy for Python programmers to write fast Python extension modules without having to learn the C language.
Cython is an actively developed derivative of Pyrex. Pyrex is no longer actively developed, the last stable release being from 2010.
