interfacing golang with python using cython

golang_to_python shows simple examples on how to create a python module coded using golang language including its wrapping interfaces written in cython. We can note that this strategy allows to simplify the wrapping interface code between golang and python by:

1. removing the awful cgo preamble code such as shown in https://blog.filippo.io/building-python-modules-with-go-1-5/,
2. improving the wrapping interface compatibility for the different versions of Python without any change of the code (e.g. no more #include Python.h header and c wrapped functions in the golang code that are usually python version dependent),
3. interfacing possibly third party libraries (e.g. numpy) into the cython script such as the associated wrapping interface can be invisible of any golang code or any python scripts (https://github.com/ryanbressler/numpy2go/blob/master/numpy2go.py),
4. removing ctypes interfaces in python scripts when golang code is compiled as a shared library,
5. making the compilation of the module just more easy,

Finally, creating a module using golang for python can just re-become simple and clean!

These simple examples have been tested with

• ubuntu-gnome
• golang = 1.9 (not tested with previous version, but get some issues with golang 1.6)
• python = 2.7
• cython = 0.26
• gcc = 5.4
