如何从Python调用Go函数

Question

I am trying to call go lang function from python when I call my python program I am seeing the following error. I am referring to the Go to pythn link.

Python Program

    from ctypes import *
    def call_go_function():

        lib = cdll.LoadLibrary("./awesome.so")
        lib.Add.argtypes = [c_longlong, c_longlong]
        print( lib.Add(12,99)) 

    call_go_function()   

Go Program

package main
import "C"
import (

"sync"
 )
 var count int
 var mtx sync.Mutex
 //export Add
 func Add(a, b int) int { return a + b }
 func main() {}

From the Python path it looks like this is a 32-bit Python version. You cannot mix 32-bit and 64-bit user-space code.

So I guess you need to either:

• Rebuild your Go code as a 32-bit DLL (see GOARCH=386) or
• Install and run a 64-bit Python version.
