Python Object-Oriented Python Dice Roller Boards

Doesn't work here, but my code works on an online compiler

Here is my code. My error message was simply "Bummer: TicTacToe' isn't itterable"

I couldn't see what I did wrong so I tested my code here: https://www.onlinegdb.com/online_python_compiler

these are the lines I added for testing:

myBoard = TicTacToe()

for item in myBoard:

print(item)

boards.py 
class Board(list):
    def __init__(self, width, height):
        self.width = width
        self.height = height
        self.cells = []
        for y in range(self.height):
            for x in range(self.width):
                self.cells.append((x, y))

    def __iter__(self):
        yield from self.cells

class TicTacToe(Board):
    def __init__(self):
        super().__init__(width=3, height=3)

Your "__iter__" code is good, but you also changed the definition of "Board" to make it a subclass of "list", which is not part of the instructions.

Put it back to being a stand-alone class and you will pass the challenge.

The code started with Board as a subclass of list...

And how would the iter method work w/o the Board class inheriting from the List class?

When you start the challenge, it gives you this initial code to work with:

boards.py 
class Board:
    def __init__(self, width, height):
        self.width = width
        self.height = height
        self.cells = []
        for y in range(self.height):
            for x in range(self.width):
                self.cells.append((x, y))

Note that the "Board" class is not a subclass of something else.

And the function of the "__iter__" method is not dependent on inheritance. Any object can be iterable.

Okay well I tried it again and your code worked. Thanks.

Glad to help, but the code is all yours. I just gave you some hints on fixing it.

Congratulations on resolving the issue, and happy coding!
