python3-pexpect 4.8.0-1 (amd64 binary) in ubuntu hirsute

 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.
