Thank you for the help. :)
----- Original Message ----
simplest way to run external commands !
import os
cmd="/usr/bin/ssh 10.0.0.20 uptime"
os.popen(cmd)
my cmd is just an example, use any cmd you want & its output will be displayed to you.
hope this helps

subprocess.Popen().communicate() will do it:
In [1]: import subprocess
In [7]: x=subprocess.Popen('ls', stdout=subprocess.PIPE,
stderr=subprocess.PIPE).communicate()
In [10]: print x[0]
....
If you just want stdout and stderr of the subprocess to go to stdout and
stderr of the calling process you can omit those arguments to Popen().
