title: python class inheritance tutorial with code examples
introduction:
inheritance is a fundamental concept in object-oriented programming (oop) that allows a new class to inherit attributes and methods from an existing class. this tutorial will guide you through the basics of class inheritance in python, demonstrating how to create a child class that inherits from a parent class.
in this example, we've defined a simple animal class with an _init_ method to initialize the name and sound attributes. additionally, there's a make_sound method that prints the sound the animal makes.
now, let's create a child class called dog that inherits from the animal class.
the dog class inherits from the animal class using the syntax class dog(animal):. the super().__init__(name, sound) line calls the constructor of the parent class to initialize the name and sound attributes. additionally, we've added a new method wag_tail specific to the dog class.
let's create instances of both the animal and dog classes and see how inheritance works.
in this example, we create an instance of the animal class and use its make_sound method. then, we create an instance of the dog class and use both the inherited make_sound method and the new wag_tail method.
class inheritance in python is a powerful feature that allows you to reuse and extend existing code. by creating a child class that inherits from a parent class, you can take advantage of the parent class's attributes and methods while adding or modifying functionality specific to the child class. this tutorial provides a basic understanding of python class inheritance with practical examples.
