I am working on the file "5-functions.ipynb".
The first task is:
use def followed by function name and parenthesized list of parameter names
we call a function and the values we pass it are assigned to those varialbes so we can use inside 
use return statement to send back result

We can now try our function out!
Can you write Python program for it?
