I keep trying to change this, but all I get back is Bummer: AttributeError: 'BookCase' object has no attribute 'book'

Not sure whats wrong

book.py 
class Book:
    def __init__(self, author, title):
        self.author = author
        self.title = title

    def __str__(self):
        return "{}, {}".format(self.author, self.title)

    def __eq__(self, other):
        return self.author + self.title == other
bookcase.py 
from book import Book 

class BookCase:

    def __init__(self):
       self.books = []

    def add_books(self, book):
        self.books.append(book)

    def __iter__(self):
        yield from self.book

Hey Madison! You are so close!

The last self.books in the __iter__ method has a typo (missing the “s”)

Post back if you need more help. Good luck!!!
