try:

Python 2.5c1 (r25c1:51305, Aug 17 2006, 17:07:04)
[GCC 3.3.6] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import subprocess
 >>> cmd = "ls"
 >>> process = subprocess.Popen(cmd, stdout=subprocess.PIPE)
 >>> print process.stdout.read()

For more info on how to do stdin and other things check out:

Hope this helps.
