🎓 About

A personal Python learning repository documenting my progress through Lecture 03: Lists & Tuples. This collection includes structured exercises, data structure manipulation practice, and an interactive student grade manager project.

---

📚 Overview

This repository contains my practice work for Lecture 03, focusing on working with lists and tuples, two fundamental data structures in Python.

---

📖 Topics Covered

✅ List Basics

• List creation and initialization
• Accessing list elements
• List concatenation and repetition
• Nested lists
• List mutability

✅ List Methods & Slicing

• Adding elements: append(), insert(), extend()
• Removing elements: remove(), pop(), clear()
• Sorting and reversing: sort(), reverse(), sorted()
• List slicing techniques
• Copying lists

✅ Tuple Basics

• Tuple creation
• Accessing tuple elements
• Tuple immutability
• Single-element tuples
• Tuple concatenation

✅ Tuple Methods & Slicing

• count()and index() methods
• Tuple slicing
• Converting between lists and tuples
• When to use tuples vs. lists

🎯 Learning Objectives

By completing this lecture, I have learned to:

• ✅ Create and manipulate lists effectively
• ✅ Use list methods for adding, removing, and organizing data
• ✅ Apply slicing techniques on lists
• ✅ Understand when to use mutable vs. immutable structures
• ✅ Work with tuples for fixed data
• ✅ Perform operations on both lists and tuples
• ✅ Build practical applications using data structures

---

💡 Practice Approach

My learning methodology focuses on:

• Understanding core concepts before jumping into code
• Attempting problems independently to build problem-solving skills
• Running & testing programs regularly in the terminal
• Experimenting by modifying values and inputs to observe behavior
• Debugging errors step-by-step to understand root causes
• Documenting learnings and observations within clean comments and code documentation
