The PyPy guys would love it if you used CFFI. Cython is also a wonderful approach. There's a lot of support of Cython, but it's also possible to find comparisons in CFFI's favour: http://eev.ee/blog/2013/09/13/cython-versus-cffi/ I've not actually used CFFI, but I've heard good things about it. > Also later on in our code development we would like to pass python lambda > functions to C++. So far I understood that this seems not to be possible. Do > you have any ideas or hints on this topics? This is definitely possible. You'll need to build C++ against CPython and use the Python C API. I've personally found that Boost::Python simplified this dramatically and IMHO if most of your code needs to use Python types directly from C++ I'd scrap Cython altogether and just use Boost. Here's some stuff on callbacks with CFFI: https://cffi.readthedocs.org/en/release-0.5/#callbacks -- https://mail.python.org/mailman/listinfo/python-list
