How to run external Python script in Golang?
问题
我想运行一个外部的Python脚本，它需要4个参数。如果我想在cmd中运行Python脚本，命令应该是这样的：python Required\Python\screenshot.py-master\screenshot.py --nojs -thumb http://google.com/ Required\Images\Screenshots\google.jpg
所以，我想从Go语言中运行这个命令。我应该如何实现呢？
谢谢。

So, I would like to run this command from Go.
How could I implement this?
Thanks.

如果文档中的示例不够有帮助，也许这个例子能让你更容易理解。
test.go:
package mainimport ("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.Stdoutcmd.Stderr = os.Stderrlog.Println(cmd.Run())}
test.py:
import sysprint sys.argv
用法:
$ go run test.go python test.py 1 two 3 four2016/02/20 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']2016/02/20 21:45:42 <nil>

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

test.py:
import sysprint sys.argv
usage:
