## Requirements

This version of Pexpect requires Python 3.3 or above, or Python 2.7.

As of version 4.0, Pexpect can be used on Windows and POSIX systems. However, `pexpect.spawn` and `pexpect.run()` are only available on POSIX, where the `pty` module is present in the standard library. See Pexpect on Windows for more information.
