Functions are a convenient way to divide your code into useful blocks, allowing us to order our code, make it more readable, reuse it and save some time. Also functions are a key way to define interfaces so programmers can share their code.
To create a function you have to start with def follow by parenthesis (), inside this parenthesis goes the parameters necessary, if needed of course, after the parenthesis goes a colon (:) and then to close it, use the return function follow by the value statement, if you don’t want it to return anything, just leave a blank space, the system will take it like None.
