Linked List Project in Python | Smart Expense Tracker (DSA Project)

Looking for a DSA project in Python?
This is a real-world Linked List project where you build a Smart Expense Tracker from scratch.


πŸ“Œ About This Project

This project demonstrates how to use Linked List in Python to build a real-world application.

Most students learn:

  • Insertion
  • Deletion
  • Traversal

But don’t know:

πŸ‘‰ β€œWhere do we actually use Linked List?”

This project solves that problem by showing a practical implementation of Linked List in an Expense Tracker system.


🎯 Who Should Use This?

  • πŸŽ“ BCA / BTech / MCA Students β†’ Perfect for Mini / Major Project
  • πŸ’Ό Job Seekers β†’ Add to resume (DSA + Project)
  • πŸ‘¨β€πŸ’» Beginners β†’ Move from theory to real-world coding

βš™οΈ Features

  • βœ… Add Expense (Create)
  • βœ… View Ledger (Traversal)
  • βœ… Delete Record (Smart Selection)
  • βœ… Filter by Amount / Date / Month
  • βœ… Summary (Total + Average)
  • βœ… Find Middle Transaction (Fast & Slow Pointer)
  • βœ… Sorted Insertion (Date-wise)

🧠 Concepts Used

  • Linked List (Custom Implementation)
  • Insertion, Deletion, Traversal
  • Fast & Slow Pointer Technique
  • Conditional Filtering (Logic Building)
  • Real-world DSA application
