Python to Go bindings using CFFI

This project shows an example of how to interface with Go from Python using CFFI (and not #import <Python.h>).

There are two main routines implemented in Go:

• Add two integers
• Sum over a Go Slice of float64s

Both functions are accessed from Go, C and Python. Additionally, Python is actually passing a NumPy array to Go. The data is never copied but simply cast to C and then wrapped in a Go Slice.

Compile and install:

git clone https://github.com/nils-werner/python-go-cffi.git
pip install -e python-go-cffi

Test:

GODEBUG=cgocheck=0 python example.py

Currently, GODEBUG=cgocheck=0 is required as we are passing C arrays to Go, which is more strict in Go 1.6 and newer. Pull requests to fix this issue are welcome!
