Python calls go code

Go 1.5 is released, which contains a feature: you can compile and build a dynamic-link library, and the resulting. So file can be loaded and invoked by Python. Here's an example:

Write a go file first main.go:

package Mainimport  "C" //export sum< span class= "token keyword" >func sum (Aintint Span class= "token operator" >{return a + B}func main{}     

Then compile go build -buildmode=c-shared -o sum.so main.go , get one sum.so and one sum.h . You can then invoke the functions in the go code with the following Python code Sum() :

#!/usr/bin/env pythonimport ctypeslib = ctypes.CDLL(‘./sum.so‘)print lib.Sum(7, 11)

With this mechanism in theory, you can use go to build more useful python modules.
