More on Classes

We use the class definition syntax that we learned from the previous lecture to build a game! First we'll design the class, i.e., our own custom type; then we implement the class in order to create a word guessing game. Along the way, we discuss how to overload special methods.

Part 1: Special methods and how to design a class

In this segment, we discuss some of Python's special methods and the steps for designing a class--a custom type.

• Code: points.py

Part 2: Class attributes and method definitions

To facilitate the creation of a word guessing game, we design and implement a class, SecretWord.

• Code: game.py, wordGuess.py, strict_wordGuess.py, friendly_wordGuess.py

Part 3: Operator overloading

We can "overload" Python operators to perform specialized operations that we define for our custom type.
