python programming with design patterns

Design patterns are reusable solutions to common problems in software design. They provide a template for solving recurring design problems and promote code reusability, maintainability, and scalability. In this tutorial, we'll explore some fundamental design patterns in Python along with practical code examples.
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 leaves the choice of its type to the subclasses, creating the object without specifying its exact class.
The Adapter pattern allows the interface of an existing class to be used as another interface.
The Composite pattern lets clients treat individual objects and compositions of objects uniformly.
