Low-Level Design in Python

This repository is a practical course on Low-Level Design (LLD) in Python, focused on applying object-oriented principles and design patterns through small, hands-on examples.

What you’ll learn

• OOP recap: Classes, objects, inheritance, composition, interfaces (via abstract base classes), and more.
• UML basics: Association, aggregation, composition, inheritance, and dependency.
• Clean low-level design: How to translate requirements into classes, methods, and interactions.
• Pythonic implementation: How common design ideas are expressed idiomatically in Python.

Additional modules, examples, and patterns will be added over time as the course evolves.

Prerequisites

• Basic knowledge of:
  • Python syntax (functions, modules, imports)
  • Classes, objects, and methods

Goals of the course

• Build intuition for designing classes and interactions before coding.
• Develop a design vocabulary (OOP, UML, patterns) you can use in interviews and real projects.
• Bridge the gap between high-level requirements and concrete Python code.

As the course grows, this README will be updated with new sections, patterns, and exercises.
