what am I doing wrong?

Its saying Book is undefined

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):
        if isinstance(other, Book):  
            return self.author == other.author and self.title == other.title  
        return False
bookcase.py 
from book import Book


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

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