Writing code is not just about making programs work — it is about making them easy to read, understand, and maintain. Clean code helps other developers (and your future self) understand what your program does.
Professional developers follow certain best practices to keep their code simple, organized, and error-free. Learning these habits early will make you a better programmer and prepare you for real-world projects.

This example shows how proper formatting and meaningful names make code easier to read and reuse.
By following clean coding practices from the beginning, students build strong professional habits and become confident, job-ready developers.
