in python, class inheritance allows you to create a new class that inherits attributes and methods from an existing class. this concept is essential for code reusability and building more complex and specialized classes. in this tutorial, we'll explore how to create a subclass that extends another class, along with code examples to illustrate the concept.
let's start by creating a base class (also known as the parent or superclass). we'll create a simple class called person that has attributes and methods related to a person's name and age.
here, the person class has an _init_ method to initialize the name and age attributes and an introduce method to introduce the person.
now, let's create a subclass (child class) that extends the person class. we'll call this subclass student. the student class will inherit the attributes and methods of the person class and add some additional attributes and methods specific to students.
in the student class, we use super().__init__(name, age) to call the constructor of the parent class (person) and initialize the name and age attributes. we also add two new methods, study and show_student_info, specific to the student class.
now, let's create instances of both the person and student classes and see how they work together.
output:
as you can see, the student class inherits the introduce method from the person class and extends it with its own methods. this is the power of class inheritance in python.
by creating subclasses that extend a base class, you can build a hierarchy of classes with specialized functionality while reusing code from the parent class. this promotes code reusability and maintainability in your python projects.
