How to run external Python script in Golang?
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

to run this command from Go. How could I implement this? Thanks.


Answer: 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
    2016/02/20 21:45:42 [/tmp/go-build772613382/command-line-arguments/_obj/exe/test python test.py 1 two 3 four]
    ['test.py', '1', 'two', '3', 'four']
