Using a class as a dictionary value in python

Certainly! In Python, dictionaries are versatile data structures that can hold various types of values, including classes or instances of classes as their values. This tutorial will explain how to use a class as a dictionary value in Python with code examples.
Let's start by creating a simple class that we'll use as a dictionary value:
The Person class has two attributes: name and age. The __repr__ method is overridden to provide a string representation of the class instances.
Now, let's create a dictionary and use the Person class instances as values:
In this example, person1 and person2 are instances of the Person class. We then create a dictionary called people_dict, where these instances are used as values with keys 1 and 2.
You can access and manipulate the class instances stored in the dictionary just like any other values:
In the above code, people_dict[1] retrieves the person1 instance, and people_dict[2] retrieves the person2 instance. It then updates the age attribute of person2 from 25 to 26.
You can also add new instances to the dictionary:
This code snippet adds a new instance, person3, to the people_dict dictionary with the key 3.
In Python, using a class as a dictionary value allows you to store instances of the class, enabling efficient organization and retrieval of related data. By understanding how to utilize classes as dictionary values, you can manage complex data structures effectively in your Python programs.
