Inheritance in Python is a fundamental concept in object-oriented programming that allows one class, known as the child class, to inherit attributes and methods from another class, referred to as the parent class. This mechanism promotes code reusability and organization, enabling developers to create a hierarchical relationship between classes. Python supports various types of inheritance, including single, multiple, multi-level, hierarchical, and hybrid inheritance. By leveraging inheritance, programmers can build more efficient and maintainable code structures, reducing redundancy and enhancing functionality. Understanding inheritance is essential for mastering Python and developing robust applications.
