Description:
Python 3 module for automating interactive applications
Pexpect is a pure Python 3 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.
