Learning-Object-Oriented-Python

This repository walks you through the Object Oriented Programming in python. Illustrates real world examples, working codes and going about finding a coding solution.

OPython-Init

A beginner-friendly collection of Object-Oriented Programming (OOP) examples in Python.

This repository aims to help learners understand OOP concepts in Python through simple, clear, and practical code examples.
It’s designed for students, self-learners, and anyone transitioning from procedural programming to Python OOP.

👥 Who Is This For?

This repository is best suited for:

• 🧑‍💻 Beginners who already know basic Python syntax (variables, loops, conditionals, functions)
• 💡 Learners who understand OOP concepts theoretically but want to see how they work in Python
• 📚 Students preparing for programming assignments or building their first Python projects

If you’ve just started learning Python and want to move beyond basic scripting — this repo is for you!

---

📘 Prerequisites

Before exploring the lessons, make sure you are familiar with:

• Writing and running Python scripts (.py files)
• Basic concepts like:
  • Variables and Data Types
  • Lists, Tuples, Dictionaries, and Sets
  • Functions and Parameters
  • If-Else Statements and Loops

If you’re missing these, you can review the new lesson: Lesson_DataStructures.py

🎯 Learning Goals

By the end of these lessons, you will:

• Understand how classes and objects work in Python
• Learn how to use constructors (__init__) and instance variables
• Implement inheritance, polymorphism, and encapsulation
• Know how to organize and reuse code using OOP design
• Write real-world examples that use OOP principles effectively

🧠 Example Lesson Format

Each lesson follows this format for clarity:

1. Concept Introduction — short description of what’s being taught
2. Code Example — simple, syntax-highlighted Python code
3. Explanation — plain-English breakdown of what happens
4. Try It Yourself — small challenge or modification to practice

Example: Defining a Class

class Student: def init(self, name): self.name = name

def greet(self):
    print(f"Hello, I'm {self.name}")

student1 = Student("Aarav")

student1.greet()
