what is best and easy way for convert maya py (python) to pyd ? 
I had explored in this field, but unfortunately none of them was effective and after convert to pyd I can't import my code into Maya.
pyd files contain native binary python extensions, usially developped using Python C API and some native language.
cython might be the simplest tool that might help you creating pyd by compiling a subset of Python source code.
What are you trying to achieve ?
