+FUNCTIONS: ONE OF THE MOST IMPORTANT PARTS OF PYTHON
+A Python function is a group of code that can be called from anywhere after it is defined. Functions can return a value using a return statement.
+ Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ). Any input parameters or arguments should be placed within these parentheses. You can also define parameters inside these parentheses.
