+This lesson explains the .capitalize() string method in Python.

+Key Points:
+1. Converts the first character to uppercase if it is a letter.
+2. Converts all other characters to lowercase.
+3. If the first character is not a letter (e.g., space, number, symbol),
+   no capitalization occurs.

 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`](./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
