Not sure how to do this .....

Not sure how to do this .....

It states it loaded a BookCase.py - why don't I see it?

Are we just assuming it's there?

Not sur show to complete this challenge

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






Book_one = Book('John Green' , 'Paper Towns')
bookcase.py
from book import Book


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

Hi there, Anthony Costanza! I feel like you might be missing that there are two files in the code challenge. When you open the challenge, you will see two dark panels. One contains the files where you write your code. The other is the "preview" window.

At the top of the first panel is a tab where it says "book.py". Right next to that is a tab with darker text because it is not in "focus" and it says "bookcase.py". You will need to click that tab to see the code for Bookcase. Each class is declared in its own file.

The code for step 3 should be written in "bookcase.py".

Hope this helps! :sparkles:
