Objects
Classes and Objects
Use class
to define a class. Then, create an object (an instance of that class).
The __init__
Method
Use __init__
to initialize an object with data when it’s created.
Attributes
Objects can store data in attributes accessed using dot notation.
Methods
Functions defined inside a class are called methods. They usually take self
as the first argument.
Object Identity
Each object is unique and has its own identity in memory.
Class vs. Instance Attributes
Instance attributes belong to one object. Class attributes are shared across all instances.
Inheritance and super()
A child class can inherit from a parent class. Use super()
to call the parent’s methods.
