What is wrong with my code?

class Book: def init(self, name, date, author): self.name = name self.date = date self.author = author

def str(self): return f"{self.name} {self.date} {self.author}"

class shelf: def init(self): self.place = []

def iter(self): yield from self.place

def add_book(self, place): self.place.append(place)

some = Book("poop", "boob", "fine")

shelf.add_book("ebby", "Jan 27th")

I am trying to have the two classes interact with each other using dunder methods. I want to be able to add a "book" to the book shelf

You might want to take a look at these videos about Posting a Question, using Markdown formatting to preserve the code's appearance, and this one about sharing a snapshot of your workspace.

Without seeing the code properly formatted, there could be other issues; but one standout is that a class should not refer to itself by name. So instead of "shelf.add_book", you probably want "self.add_book".

Also, why would the code create a book named "some", but then not use it?

And it looks like "add_book" is being called with 2 arguments, but it's only defined to take one.
