You might want to have a look at "cython".

"cython" is a compiler compiling source programs in a Python
extension into "C". The corresponding "C" functions can
then be called from "C" (you may need to annotate the
functions used in this way to get proper "GIL" ("Global Interpreter Lock")
handling).
