Python Object-Oriented Python Dice Roller Boards

What I'm doing wrong here? The error message "TicTacToe" isn't iterateable doens't help.

The error messages doesn't help me in anyway. Because even if I'm changing something in the superclass (Board) it still says "TicTacToe isn't iterateable". Obviously this is true but it doens't help to find the mistake.
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))

    def __iter__(self):
        yield from self.cells

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

    def __iter__(self):

It's complaining that "TicTacToe isn't iterable" because the __iter__ method doesn't return anything.

Now you could fix that, but even easier you can simply remove the __iter__ method from "TicTacToe" and allow it to inherit the one you (correctly) implemented for "Board".
