I am using pexpect and I want to send output of pexpet to both stdout

know.

One way is to create a file-like object that forked the output to stdout
and the logfile.

class forkwriter(object):
def __init__(self, filename):
self.file = open(filename, 'w')
def write(self, s):
sys.stdout.write(s)
self.file.write(s)

I've never used pexpect myself though, but if pexpect write things to the
to the stdout, then you can redirect stdout

import sys
sys.stdout = forkwriter('mylog.log')

(note: the forkwriter class would have to be modified a bit to use the
"background" sys.__stdout__ instead of sys.stdout)
