Before jumping to writing C extensions, use Numeric 
(http://www.pfdubois.com/numpy/). Chances are it will give you enough speed 
(close to C) without ever dropping out of python.

Doing any 'real' math-oriented work in python is almost guaranteed to need 
Numeric at some point, so you might as well start using it now. It will save 
you a lot of time.
