subprocess.Popen在不同的控制台中 [英] subprocess.Popen in different console

问题描述

我希望这不是重复的内容.

I hope this is not a duplicate.

我正在尝试使用subprocess.Popen()在单独的控制台中打开脚本.我试过设置shell=True参数，但没有成功.

I'm trying to use subprocess.Popen() to open a script in a separate console. I've tried setting the shell=True parameter but that didn't do the trick.

我在64位Windows 7上使用32位Python 2.7.

I use a 32 bit Python 2.7 on a 64 bit Windows 7.

推荐答案

from subprocess import *

c = 'dir' #Windows

handle = Popen(c, stdin=PIPE, stderr=PIPE, stdout=PIPE, shell=True)
print handle.stdout.read()
handle.flush()

如果不使用shell=True，则必须为Popen()提供列表而不是命令字符串，例如:

If you don't use shell=True you'll have to supply Popen() with a list instead of a command string, example:

c = ['ls', '-l'] #Linux

，然后在没有外壳的情况下将其打开.

and then open it without shell.

handle = Popen(c, stdin=PIPE, stderr=PIPE, stdout=PIPE)
print handle.stdout.read()
handle.flush()

这是您可以从Python调用子流程的最手动，最灵活的方法. 如果只需要输出，请执行以下操作:

This is the most manual and flexible way you can call a subprocess from Python. If you just want the output, go for:

from subproccess import check_output
print check_output('dir')

要打开新的控制台GUI窗口并执行X:

import os
os.system("start cmd /K dir") #/K remains the window, /C executes and dies (popup)
