Functions
Once you get the hang of writing functions and putting your code inside functions (modular programming) your programming skills will move up to the next level. Functions help organise code and are important in coding.
Note: For learning purposes keep in mind that a function is defined as a subroutine that returns a value e.g. an integer value 1. In Python subroutines that are not functions are often referred to as functions.
