Appending to a list
You've been provided with a dictionary called authors, which has information about 20 of the most popular fiction authors in the World. It contains the names of authors as keys and the number of books they've created as values.
You're interested in finding out how many of these authors have made less than 25 books. To do this, you will create a list called authors_below_twenty_five, filling it with author names conditionally based on whether they have created less than 25 books.
