Single-parameter functions

Congratulations! You have successfully defined and called your own function! That's pretty cool.

In the previous exercise, you defined and called the function shout(), which printed out a string concatenated with '!!!'. You will now update shout() by adding a parameter so that it can accept and process any string argument passed to it. Also note that shout(word), the part of the header that specifies the function name and parameter(s), is known as the signature of the function. You may encounter this term in the wild!
