Hi, I am writing an extention module in C. Well I'm writing the low level (math
intensive) stuff in C and want to wrap it up in some native python classes for
a nice api. Should I write it as two seperate modules (the compiled C one and
the native python one) or is there a way to combine them in one. I am using the
SWIG program to wrap my C library.

Help apreciated.

It is often the practice to put make a Python module that imports a C
module. That's what I'm doing with Multipack
http://oliphant.netpedia.net/multipack.html
You can construct C-modules that don't need a Python wrapping, however, it
is easier to handle the user-end API in Python.

If you are doing math intensive calculations, have you looked at the
Numeric extensions?

Good luck,

Travis
