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
