Try with this example:

import subprocess

proc = subprocess.Popen(['/bin/bash'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
stdout = proc.communicate('ls -lash')

print stdout

You have to read more about stdin, stdout and stderr. This looks like good lecture: http://www.doughellmann.com/PyMOTW/subprocess/

EDIT:

Another example:

>>> process = subprocess.Popen(['/bin/bash'], shell=False, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
>>> process.stdin.write('echo it works!\n')
>>> process.stdout.readline()
'it works!\n'
>>> process.stdin.write('date\n')
>>> process.stdout.readline()
