Title: Creating a Class with Another Class Object in Python
Introduction:
In Python, it is possible to define a class within another class, a concept known as nested or inner classes. This approach can be useful in various scenarios, providing a way to encapsulate related functionality within a parent class. In this tutorial, we'll explore how to define a class with another class object in Python, along with a practical code example.
Example Scenario:
Let's consider a scenario where we have a University class that contains a nested Student class. The University class will have attributes such as university name and location, while the Student class will represent individual students with attributes like name, age, and course.
Explanation:
University Class: The outer class represents the university and has attributes like name, location, and a list to store student objects.
Student Class (Inner Class): The nested class, Student, is defined within the University class. It contains attributes like name, age, and course, along with a method to display student information.
Initialization: The _init_ method in both classes is used to initialize the attributes.
Adding Students: The add_student method in the University class demonstrates how to create and add a Student object to the list of students.
Usage Example: In the usage example, we create a University instance, add students, and then display information about each student.
Conclusion:
Defining a class with another class object in Python can help organize and encapsulate related functionality. This tutorial provides a basic example, and you can extend this concept based on your specific use cases.
