Yup I use the pexpect module for a lot however couldn't get 'pexpect.run' to work with mysqldump piping to gzip

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()
