Basic OOP Python. Emulating Built-Ins, Task # 3

Getting this error here:

AssertionError: False is not true : Make sure you have a __iter__ method in your class

book.py 
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.books
bookcase.py 
from book import Book


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

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

The code looks good, but it is in the wrong place.

Unlike tasks 1 and 2 which are both done in the Book class, the instructions say that task 3 is to be done in the "Bookcase class inside bookcase.py".

Ahh, I was wondering about that! Didn't realize that preview page had two tabs. Thanks Steven.
