Python Functions for Beginners: Return vs Print & Reusable Code | Python Tutorial #21

YouTube Excerpt: Functions are the building blocks of efficient programming. In Lesson 21, we unlock the power of reusable code! You'll learn how to break your programs into small, organized pieces that make your code easier to read, debug, and maintain. We start by defining basic functions using the def keyword and explore the critical difference between "Returning" a value and "Printing" it to the console. If you've ever wondered why your variables keep returning 'None', this video has the answer! We also build a custom reversal function that works on strings and lists alike.
