-Functions are blocks of code that can be reused simply by calling the function. This enables simple, elegant code reuse without explicitly re-writing sections of code. This makes code both more readable, makes for easier debugging, and limits typing errors.

 Functions in Python are created using the `def` keyword, followed by a function name and function parameters inside parentheses.

 ### Recursion
 Using functions in our programs can help to explicitly handle the execution of specific type of algorithms.
