What is Python Class Definition?
A Python class definition is a blueprint for creating objects in object-oriented programming. It encapsulates data attributes and methods that define the behavior of the objects instantiated from the class. A class is defined using the `class` keyword, followed by the class name and a colon. Inside the class, you can define instance variables and functions (methods) that operate on those variables. Classes promote code reusability and organization, allowing developers to model real-world entities and their interactions effectively. By using classes, programmers can create complex applications with modular and maintainable code structures.
