subprocess.Popen in different console

Question

I hope this is not a duplicate.

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.

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

Answer 1

To open in a different console, do (tested on Win7 / Python 3):

from subprocess import Popen, CREATE_NEW_CONSOLE  Popen('cmd', creationflags=CREATE_NEW_CONSOLE)  input('Enter to exit from Python script...')

Answer 2

from subprocess import *  c = 'dir' #Windows  handle = Popen(c, stdin=PIPE, stderr=PIPE, stdout=PIPE, shell=True) print handle.stdout.read() handle.flush() 

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 

and then open it without shell.

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

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')
