design patterns in python code

Design patterns are reusable solutions to common problems encountered in software design. They represent best practices evolved over time by experienced developers. In this tutorial, we'll explore some popular design patterns and demonstrate how to implement them in Python.
The Singleton pattern ensures that a class has only one instance and provides a global point of access to it.
The Factory Method pattern defines an interface for creating an object but lets subclasses alter the type of objects that will be created.
The Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified.
Design patterns provide a structured way to solve common design problems. The examples provided here cover just a few of the many design patterns available. By understanding and applying design patterns, developers can create more maintainable, scalable, and flexible software solutions. Experiment with these patterns in your projects to gain a deeper understanding of how they work in different scenarios.
