   Do low-level stuff in low-level languages, and high-level stuff in high
lavael languages.

   Do number crunching in C, compile your code into a python module using
compiler optimisation, link with optimised (both in terms of algorithms and
compiler) math library.
   And glue all your modules together with Python!
