Python Design Patterns

Welcome to the Python Design Patterns repository! This project serves as a collection of commonly used design patterns implemented in Python, helping developers solve recurring problems efficiently and elegantly.

---

🚀 Purpose

The goal of this repository is to provide:

• A practical reference for design patterns in Python.
• Examples of real-world applications of patterns.
• Insight into the advantages and limitations of each pattern.

🗂️ Patterns Covered

Creational Patterns

• Singleton: Ensures only one instance of a class is created.
• Factory Method: Delegates object instantiation to subclasses.
• Abstract Factory: Provides an interface to create families of related objects.
• Builder: Constructs complex objects step by step.
• Prototype: Creates new objects by cloning existing ones.

Structural Patterns

• Adapter: Bridges two incompatible interfaces.
• Decorator: Dynamically adds behavior to objects.
• Proxy: Controls access to an object.
• Composite: Treats individual objects and compositions of objects uniformly.
• Bridge: Separates abstraction from implementation.
• Facade: Provides a simplified interface to a complex subsystem.

Behavioral Patterns

• Observer: Defines a subscription mechanism to notify multiple objects of state changes.
• Strategy: Encapsulates interchangeable behaviors and algorithms.
• Command: Encapsulates a request as an object.
• State: Manages object behavior based on its state.
• Template Method: Defines the skeleton of an algorithm in a method.
• Chain of Responsibility: Passes requests along a chain of handlers.
