Linked Lists Implementation in Python (Tamil) 🔥 | Add, Traverse, Length, Multiple Nodes | DSA Day 5

Welcome to Day 5 of the DSA Master Series.
In this episode, we shift from theory to practice and implement a complete Linked List in Python with clear explanations, diagrams and real logic.

If you struggled to understand how Linked Lists actually work behind the scenes, this video will make everything click. You will learn how nodes connect, how memory works and how real-world systems store dynamic data.

🔥 What You Will Learn in Day 5
• Linked List diagram with pointers and node structure
• What classes and objects are in Python
• How to define your own Linked List class
• How to add a single node to the list
• How constructors (init) work in Linked List creation
• How to traverse a Linked List step by step
• How to add multiple nodes dynamically
• How to add a list of values at once
• How to compute the length of a Linked List

💡 Why This Matters
Linked Lists form the base for advanced structures like Stacks, Queues, Graph adjacency lists, memory allocation systems and OS scheduling.
If you master Linked Lists, your DSA fundamentals will become much stronger and your coding confidence will grow instantly.
