Write a simple function

In the last video, Hugo described the basics of how to define a function. You will now write your own function!

Define a function, shout(), which simply prints out a string with three exclamation marks '!!!' at the end. The code for the square() function that we wrote earlier is found below. You can use it as a pattern to define shout().

def square():
    new_value = 4 ** 2
    return new_value

Note that the function body is indented 4 spaces already for you. Function bodies need to be indented by a consistent number of spaces and the choice of 4 is common.

This course touches on a lot of concepts you may have forgotten, so if you ever need a quick refresher, download the Python for Data Science Cheat Sheet and keep it handy!
