Do you ever have problem while execute /usr/bin/passwd from your python code? actually i have problem with changing unix password from my python code.

First i try using pipe to control output from /usr/bin/passwd, hopefully i can send text with write() function.
this is the code :

#!/usr/bin/python
import os
COMMAND = 'passwd'
PASSWD  = 'mypassword'

# open a pipe to passwd program and
# write the data to the pipe
p = os.popen("%s" % COMMAND, 'w')
p.write(PASSWD)
p.write('n')
p.write(PASSWD)
p.close()

The solution is use Pexpect
