Pexpect makes Python a better glue for controlling child applications.

Pexpect is a pure Python module for spawning child applications;
controlling them; and responding to expected patterns in their
output. Pexpect works like Don Libes' Expect.  Pexpect allows your
script to spawn a child application and control it as if a human were
typing commands.

Pexpect can be used for automating interactive applications such as
ssh, ftp, passwd, telnet, etc.  It can be used to a automate setup
scripts for duplicating software package installations on different
servers.  It can be used for automated software testing.  Pexpect is
in the spirit of Don Libes' Expect, but Pexpect is pure Python.  The
Pexpect interface was designed to be easy to use.
