Low-Level Design💡

The goal of this repository is to get better understanding of Design Patterns, Low-Level Design, SOLID principles and Object-Oriented Programming (OOP) concepts in Python. It contains various case studies and their implementations in Python.

Fundamentals 📚

This section contains implementation from some basic concepts in Python to advanced topics like Dynamic Protocols and Meta Programming.

• OOP in Python
  • Python Basics
  • Classes
  • Dunders
  • Properties
  • Inheritance
  • Slots
  • Dataclasses
  • Descriptors
  • Enums
  • Exception
  • Dynamic Protocols
  • Abstract Base Classes
  • Multiple Inheritance
  • Meta Programming

SOLID Principles 🛠️

This section focuses to show the importance of SOLID principles. It contains the before examples to show a class violating the principle, while the after examples show a refactored class adhering to the principle.

• Single Responsibility
• Open/Closed
• Liskov Substitution
• Interface Segregation
• Dependency Inversion

Design Patterns🎨

This section shows an example implementations of standard design patterns that are handled in a certain way to recurring problems in software design.

Creational Patterns

• Singleton
• Factory
• Abstract Factory
• Builder
• Prototype

Structural Patterns

• Adapter
• Bridge
• Composite
• Decorator
• Facade
• Flyweight

Behavioral Patterns

• Observer
• Strategy
• State
• Chain of Responsibility

Design Problems 🚀

This section features some real-world design challenges that allows to put object-oriented programming, design patterns, and SOLID principles into practice. Each project simulates a common software scenario, offering hands-on experience to refine low-level design skills.
