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): super().__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".
