Introduction

When you think of python projects for your VTU CSE/Computer Science Engineerin, web apps or machine‑learning comes to your mind. Sometimes the most intersting and rewarding projects like banking or ATM. Building a Simple ATM Machine in Python, fundamental programming concepts like control flow, functions and file handling also gives you a tangible, real‑world simulation to showcase in your portfolio.

In this article, we’ll explore why an ATM project makes for a standout project, compare it with other popular Python assignments, uncover technical best practices, and share personal experiences that’ll help you avoid common issues. You can watch youtube video also, if you not able to understand how to use given code and make your own project.
