Classes and objects are fundamental concepts in Python from "summary" of Python For Dummies by Stef Maruch,Aahz Maruch
Classes and objects are fundamental concepts in Python. Classes are a way of bundling data and functionality together. When you define a class, you create a new type of object, allowing you to create new instances of that type. Objects are the instances of classes. Every object is an instance of a specific class, and every class has at least one object. A class is like a blueprint for an object. It defines the data and behavior that the object will have. The data is stored in attributes, and the behavior is defined by methods. Attributes are variables that belong to the object, while methods are functions that belong to the object. When you create an object, you are creating an instance of that class, with its own set of attributes and methods. Classes are defined using the `class` keyword, followed by the class name. Inside the class, you can define attributes and methods. To create an object from a class, you use the class name followed by parentheses. This calls the special method `__init__`, which initializes the object and sets its initial state. Objects can interact with each other through their methods. When you call a method on an object, the method can access the object's attributes and modify its state. This allows objects to communicate with each other and collaborate to achieve more complex tasks. By using classes and objects, you can write more modular and reusable code, making your programs easier to understand and maintain.
