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!

Complete the function header by adding the appropriate function name, shout.
In the function body, concatenate the string, 'congratulations' with another string, '!!!'. Assign the result to shout_word.
Print the value of shout_word.
Call the shout function.
