Question

Hi Stack Overflow users,

I\'ve encountered a frustrating problem, can\'t find the answer to it.

Yesterday I was trying to find a way to HIDE a subprocess.Pop

Answer 1

python 3.1.3 > and 2.7

import subprocess
import sys

params = dict()
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
params['startupinfo'] = startupinfo

p = subprocess.Popen("cmd.exe", **params)
