it to faster running code.
I have a fairly long-running simulation that is mostly done in Python (with some numpy and scipy under the hood). I decided to try Cython and it sped it up by about 50%. It won't speed up any of the stuff under the hood that is already in C (like much of numpy and scipy), but it will speed up any of your own loops.
It was as easy as renaming my file to .pyx, finding the standard setup.py to run Cython on it. It creates a shared library that can then just be imported and the python code inside of it being available to the interpreter.
Wish I would have known about this a long time ago.
