Python Classes Objects Special Methods Inheritance Polymorphism Session 16: inheritance & polymorphism in python polymorphism high level explanation polymorphism means 'many forms'. it allows different classes to have methods with the same name but different behavior. two types: method overriding and method overloading. Polymorphism is an important feature of class definition in python that is utilized when you have commonly named methods across classes or subclasses. this permits functions to use entities of different types at different times.
Polymorphism In Python Pdf Inheritance Object Oriented Programming Inheritance is a fundamental concept in object oriented programming (oop) that allows a class (called a child or derived class) to inherit attributes and methods from another class (called a parent or base class). example: here, a parent class animal is created that has a method info (). then a child classes dog is created that inherit from animal and add their own behavior. Inheritance example explanation of the previous example: single inheritance: labrador inherits dog’s attributes and methods. multilevel inheritance: guidedog extends labrador, inheriting both dog and labrador functionalities. multiple inheritance: goldenretriever inherits from both dog and friendly.

Abstract base classes first, we need to tell python that our class is supposed to be an abstract base class. this way it will know to enforce the rules for others to inherit from it. to do this we have our class inherit from the abcclass of the abc module. Inheritance, polymorphism, abstract classes in oop, inheritance is the mechanism of deriving (inheriting) the properties from another class. it allows us to de±ne a child class that inherits all the methods and properties from a parent class. Objectives • understand the purpose and principles of inheritance, super classes and sub classes • be able to declare and use a subclass • understand polymorphism and how it can be achieved • understand how to override parent attribute and methods key vocabulary: inheritance, inheritance diagram superclass, subclass, polymorphism. Code example demonstrating inheritance and polymorphism: inspired by the examples of automobiles and animals creating noises, let’s use a python programming example to demonstrate these ideas.
