Sudoku is actually a pretty easy problem computationally, I'd do the whole
thing in Python, unless you aren't as comfortable doing fancy algorithms
(usually easier, anyway, unless you aren't used to the language, or really
need static typing) in Python.. but then this would be a good opportunity to
overcome that :)
Or you're doing large boards, generating puzzles in bulk, or something like
that that multiplies the computational effort. The GNOME Sudoku is written in
Python, by the way.
There's tons of ways to interface C and Python. You can access the Python API
directly: http://docs.python.org/extending/index.html; this is not for the
faint of heart, but it provides maximum control and you learn a lot about
Python internals on the way!
Write your C code as a library and use SWIG to wrap it up into a Python
module: http://www.swig.org/; this can get interesting if you have
complicated call signatures, I sometimes avoid it and go right to the API,
since I'm comfortable there :)
If your code is C++, you can do something similar with Boost::Python:
http://www.boost.org/doc/libs/1_47_0/libs/python/doc/; I've never used it, but
it's there. Note that SWIG works fine with C++ libraries.
There's always the Python-C hybrid, Cython: http://cython.org/; I haven't
waded into its waters yet, either.
But I'd recommend doing it all in Python, for the exercise, if nothing else,
unless you have a good reason not to.
