Hierarchical inheritance in Python lets you create a family tree of classes. It's like having a parent class that passes down traits to multiple child classes, each with their own unique features.
This powerful tool helps you organize and reuse code efficiently. You can build complex class structures, from general to specific, allowing for flexible and modular programming in object-oriented design.

Class structure design for inheritance
Multilevel inheritance for tree-like organization
Involves creating a hierarchy of classes with multiple levels
Base class (Animal) serves as parent for one or more derived classes (Mammal )
Derived classes can serve as parent classes for further derived classes (Cat and Dog inherit from Mammal)
Each class in hierarchy inherits attributes and methods from its parent class
Allows for creation of tree-like structure of classes (Animal → Mammal → Cat/Dog)
When accessing attributes or methods, Python searches in current class, then parent class, and continues up hierarchy until found or top reached (method resolution order )
Cat object can access eat() method defined in Animal class
Enables creation of increasingly specialized classes
Each level in hierarchy adds more specific attributes and behaviors (Mammal class adds nurse() method, Cat class adds meow() method)
Object-Oriented Programming Concepts in Hierarchical Inheritance
Inheritance: Allows classes to inherit attributes and methods from other classes
Encapsulation : Bundles data and methods that operate on that data within a single unit or object
Subclass: A class that inherits from another class, also known as a derived class
Superclass: A class from which other classes inherit, also known as a base class
