You're not specifying the command to Popen correctly (a very common problem).

(Shameless plug: I *really* wish someone would look at my docs patch
to explain this common problem -- http://bugs.python.org/issue6760)

Corrected code:

cmd = [p4, 'passwd', user]
pipe = Popen(cmd, shell=True, stdin=PIPE, stdout=PIPE, stderr=PIPE,
universal_newlines=True)

Though your code may have other problems too (I didn't check).

Cheers,
Chris
