This document discusses using classes to create custom objects and text adventures in Python. It introduces classes and how they can be used to define objects with their own attributes. It then tasks the reader with looking at an Animals.py example file to see how classes are defined for different animal types like giraffe and horse. The reader is also instructed to create their own instance of an animal class and give it attributes, then use a design sheet to plan and create their own text adventure game in Python.
