I keep getting a NameError and it says "Book" is not defined. I can't figure it out.

Add a eq method for this book class. It should check if the author and title of the book are the same and return true if they are and false if they aren’t.

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
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)
