Go compiles the so library and lets python references do not have .h files after compilation

Sometimes python needs to refer to some open source libraries of go, and then go needs to be compiled into a callable library for python.

go code

package main//The package must be main
import(
	"C"//Requires support from C library to facilitate type conversion)

func main(){}

//It's very important, export means mapping Go functions to Python function calls//If there is no export, then the .h file cannot be generated, and python cannot call the function
//export HelloWorld
func HelloWorld() * {
	return ("i'm zero wood")
}

Very important, export means mapping Go functions to Python function calls
If there is no export, then the .h file cannot be generated, and python cannot call the function

Go compiled into a python call library, the compilation environment is ubuntu18.04.1 LTS

Compile commands

go build -buildmode=c-shared -o

A file will be generated

Then there are functions in python calls

import ctypes

lib = ("./")

helloWorld = 

 = ctypes.c_char_p

print(helloWorld())
