Inheritance of Classes: Fundamentals of Class Inheritance in Python's Object-Oriented Programming

Python class inheritance is a core feature of object-oriented programming, enabling the reuse of parent class attributes and methods while extending functionality by creating subclasses. Its primary goal is to address code redundancy and implement reuse, extension, and structural simplification. Basic Syntax: First, define a parent class (e.g., `Animal` with a `name` attribute and an `eat` method). A subclass (e.g., `Dog(Animal)`) inherits all attributes and methods of the parent class through inheritance and can additionally define new methods (e.g., `bark`). For example, an instance of `Dog` can call both the parent class method `eat` and the subclass method `bark`. Method Overriding: A subclass can define a method with the same name to override the parent class. For instance, `Dog` overrides the `sleep` method, using `super().sleep()` to invoke parent class logic. Python supports single inheritance (common, e.g., `class Dog(Animal)`) and multiple inheritance (with attention to method resolution order, MRO). The core roles of inheritance are reuse, extension, and clear structural organization, laying the foundation for polymorphism. Mastering syntax, method overriding, and the use of `super()` is key.
