- 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—are also available on
- Windows.
