The main advantage of using Cython for glue code is that you don't need to touch the Python/C API, it generates the necessary code for you (in particular it handles the reference counting). (I like to think of Cython as 'C with easy access to the Python runtime'.) However, the API certainly doesn't look scary in these examples (I've never really used it). Admittedly I didn't consider SWIG, so thanks for that. It would be nice to be rid of the Cython glue layer, so I might try that. Of course that would mean writing much of the glue (sanity checking) in C++ or Python instead of Cython.
