class Book:
def __init__(self, author, title):
self.author = author
self.title = title
def __str__(self):
return f'{self.author}, {self.title}'
def __eq__(self, other):
return self.author == other.author and self.title == other.title
def __iter__(self):
yield from self.book
from book import Book
class BookCase:
def __init__(self):
self.books = []
def add_books(self, book):
self.books.append(book)

If you switch "tabs" and add the __iter__() method there. You will solve the Challenge.
Good luck with your Python journey!
