If you're doing that then you *really* want to be using the pexpect
module.

cmd = pexpect.spawn('su - SOMEINTERACTIVECOMMAND')
cmd.expect('# ')   # the prompt
cmd.sendline('A COMMAND')
cmd.expect('# ')   # wait for the prompt again
output = cmd.before  # the stuff before the prompt
cmd.sendline('exit')
cmd.close()
