You can do this in various ways, ranging from the very simple and not very good

from commands import getoutput

x=getoutput(command)


- to your more common and better popens.

ie:

import popen2

(stdOut, stdIn) = popen2.popen4(command)

x=stdOut.readlines()

- asynchronously if appropriate.

How are you running the command at the moment?
