Cluto like library for Python

[Miki Tebeka]

You have several option for interfacing with C libraries: Cython, swig, boost-python, ctypes ...

You can find several machine learning packages mentioned at http://web.media.mit.edu/~stefie10/technical/pythonml.html, I have no experience with any of them so I can't recommend any.
