Tee'ing Python subprocess.Popen output

A little hack for python coders out there who wanted to have a functionality similar to the unix's tee command for redirecting output to multiple places.

import sys
from subprocess import Popen,PIPE
p = Popen(['put','command','and','arguments','here'],stdout=PIPE)

while True:
   o = p.stdout.readline()
   if o == '' and p.poll() != None: break
   # the 'o' variable stores a line from the command's stdout
   # do anything u wish with the 'o' variable here
   # this loop will break once theres a blank output 
   # from stdout and the subprocess have ended
