12,027 Pointsthis part of the code is an error some how def eq(self, other): if isinstance(other, Book): return self.author == other.author and self.title == other.title return False

Treehouse Project ReviewerHey there terencelewis !
You're super close here! It just needs a little adjustment. The challenge reads "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." So I believe the isinstance check you had in place is what was throwing the answer validation on the back end off.
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
