A class groups closely related data and behavior into a reusable template. Creating an instance turns its data into object state and its behaviors into methods. section 2.2.2 section 2.3
In Python, a class commonly provides:
- Attributes that hold an instance’s state. section 2.2.2
- Methods that receive self and can read or change that state. section 2.2.2
- An __init__ initializer that establishes initial state when an instance is created. section 2.2.2
Refactoring a game into a class
A Rock, Paper, Scissors program begins with functions that repeatedly share choices and game data. A RockPaperScissorsSimulator class gathers those behaviors, stores human_choice and computer_choice, and lets simulate coordinate the interaction through self. An instance can then run the game with RPS.simulate().
