Homework

1. Modify the code we wrote in class with the following instructions: https://drive.google.com/drive/folders/1Gy-hd4QHOnQKmmT_lL164JMiWypBBbv8
2. Create find book by ID
   1. Create a new attribute: a dictionary named id_to_book
   2. In the add_book() method, also add the book to the id_to_book dictionary
   3. Create a method find_book_by_id — this is going to look exactly like find_book_by_name, but with the id_to_book dictionary instead of book_dictionary
3. Create list all old books
   1. Go through the dictionary values. If the book was written before 2000, print it out. Otherwise, don’t print anything out.
