A convenient way for Golang to call Python libraries

For some reason, the Python library is not easy to implement with Golang refactoring, so we can do this by calling the Python library via Go

• Call Python as a shell command assembly

It mainly uses the GO OS /exec package and python’s -c arguments

func main(point int) {
	var err error
	var cmd *exec.Cmd
	var datas []byte
	py := "python"
	flag := "-c"
	importmodule := "import sys"
	Target := "print(sys.path)"
	params := fmt.Sprintf("%s; %s", importmodule, Target)
	fmt.Println(params)
	cmd = exec.Command(py, flag, params)
	ifdatas, err = cmd.Output(); err ! =nil {
		fmt.Println(err)
		os.Exit(1)
	}
	fmt.Println(string(datas))

}
}
Copy the code

Similarly, when using other self-written Python libraries, add the Python code path to the sys.path path before making the call.
