Seems like task 2 is bugged. I ran my class & the dunder eq method in an outside text editor and it works fine.

I ran my class & the dunder eq method in an outside text editor and it works fine. But when I submit the same code I get an error that is difficult to understand.

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):
    return (self.author == other.author and self.title == other.title)

Code is up above.

book.py
class Book:
    def __init__(self, author, title):
        self.author = author
        self.title = title
bookcase.py
from book import Book


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

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

Hey Harris! No problem at all! Our challenges are graded using a regex answer. So, if the answer isn't formatted a specific way, it will throw an error. While there may be nothing wrong with the code that is entered, the syntax matters for the final answer in our code challenges.

Hey HARRIS SPAHIC Your code looks great, but it looks like you have a space between __eq__ and (self, other), which is causing this particular challenge to fail. Great job solving the challenge!

Oh wow, thank you for the catch! If you don't mind me asking, I'm curious as to why that space is relevant in what I'm assuming is a web-based IDE, rather than a text editor running python?
