Reviewing Functions Quiz question

The question says "there is a code smell in the code below:

first_number = 5 first-result = first_number * first_number print("The number {} squared is {}".format(first_number, first_result))

second_number = 8 second_result = second_number * second_number print("The number {} squared is {}".format(second_number, second_result))

It then asks "What could be done to fix the duplication of code?"

I understand that the answer is to create a function and have it accept a parameter of a number to square. However when I tried to actually code it in workspace to figure it out I wasn't sure how to do it. Could some one show me what the code would look like to actually fix this smelly code. Thanks

(P.s. Is there a way to show the question without having to type it out?) thanks

There are a couple of different ways this could be coded, but here is the code I would have written:

def print_square(number):
    print("The number {} squared is {}".format(number, number * number))


That is one of the simplest solution I could think of, and it looks relatively clean.
