Practical Python: Learn Python Basics Step by Step- Python 3 - Function Return Statement

The video tutorial explains how to create functions in programming, focusing on making them dynamic and capable of returning values. It demonstrates creating a function that doubles a number and optimizes it by directly returning the result. The tutorial also covers different types of functions, including those that perform actions without returning values and those that return various data types. Additionally, it illustrates how functions can be used as building blocks by calling one function within another, enhancing modularity and reusability in code.
