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 main features of Pexpect require the pty module in the Python standard
library, which is only available on Unix-like systems. Some features -- waiting
for patterns from file descriptors or subprocesses -- waiting for patterns from
file descriptors or subprocesses.
