Your code is valid, it just has a syntax error. If you inspect the error message on the right, you'll see it's pointing to the end of your return conditional line. Having a break like this will cause an error. So you just need to put them back to the same line like so...
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
