I'll second ctypes. It's pretty straightforward and I've made it do
some very heavy lifting over the years. Cython is definitely more work.
SWIG makes sense if you've got a huge number of interfaces you're trying
to map and need to automate the process, but if you've got south of 20
I'd just do it natively with ctypes.
