>That's not so easy. Interfacing Python and C code is also incredibly hard, and no one true way exists.
Can you elaborate on this. I've worked on python C extensions (just minor updates and fixes, I've never been the one to write significant chunks of it), and it seems like interfacing python with C is pretty straight forward.
If you use the CPython C API it's easy - but you also bind yourself closely to CPython. If you know performance is going to be important it's probably better to bite the bullet and use PyPy - which means you have to use the somewhat cruder cffi to interface with C code.
