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 self.author == other.author and self.title == other.title :
return True
else :
return False
from book import Book
class BookCase:
def __init__(self):
self.books = []
def add_books(self, book):
self.books.append(book)

The spaces before the colon in the eq method are the reasons for your error, in addition to the fact that there's no space after the comma between the parens.
Make it so that your code looks like the code below, and you should pass the challenge.
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 self.author == other.author and self.title == other.title:
return True
else:
return False
Python is a language where indentation and whitespace are important.
Hope that helps.
