486 Pointswhats wrong with the code
I have seen that everything from ,y example when i went through the code is the same so i dont understand what is happening
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
from book import Book
class BookCase:
def __init__(self):
self.books = []
def add_books(self, book):
self.books.append(book)
def __iter__(self):
yeild from self.books

Treehouse StaffHey Caleb James 👋
Looks like you got a typo in your __iter__
method, it says yeild
instead of yield
🙂
Fixing that should fix the issue and pass your code as expected 😃
