如何在Golang中运行外部Python脚本？

Question

I would like to run an external Python script that gets 4 arguments. If I would like to run the Python script in cmd it would look like this: python Required\Python\screenshot.py-master\screenshot.py --nojs -thumb http://google.com/ Required\Images\Screenshots\google.jpg So, I would like to run this command from Go. How could I implement this? Thanks.

If examples from doc are not helpful, maybe this will make it easier for you.

test.go:

package main

import (
    "log"
    "os"
    "os/exec"
)

func main() {
    log.Println(os.Args)
    if len(os.Args) == 1 {
        return
    }
    cmd := exec.Command(os.Args[1], os.Args[2:]...)
    cmd.Stdout = os.Stdout
    cmd.Stderr = os.Stderr
    log.Println(cmd.Run())
}

test.py:

import sys
print sys.argv

usage:

$ go run test.go python test.py 1 two 3 four
