Python Classes: The Power of Object-Oriented Programming
- Python classes form the backbone of object-oriented programming, enabling you to encapsulate data and behavior into a single entity.
- A class in Python serves as a blueprint for creating objects, which are instances of the class.
- By defining classes, you can create multiple objects that share the same attributes and methods, while maintaining their own unique state.
- Methods define behaviors, while attributes store data within class instances.
- Instance attributes are unique to each object, while class attributes are shared across all instances of the class.
- To define a class, you need to use the class keyword followed by the class name and a colon.
- Attributes are variables defined inside a class with the purpose of storing all the required data for the class to work.
- Methods are functions that you define within a class.
- In Python, the body of a given class works as a namespace where attributes and methods live. You can only access those attributes and methods through the class or its objects.
- As an example of how to define attributes and methods, say that you need a Circle class to model different circles in a drawing application.
