Also one should beware that ctypes is a stable part of the Python 
standard library.

Cython is still unstable and in rapid development.

Pyrex is more stabile than Cython, but interfacing with ndarrays is harder.

If you have a requirement on not using experimental code, then Cython is 
not an option.
