Help in OOP Board in challenge Task 2 of 2

I am stuck in the challenge task 2 of 2, when I submit my code, it says 'Tic Tac Toe' Isn't iterable, what did I do wrong, and how do I solve this problem

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))

class TicTacToe(Board):
    def __init__(self,width=3,height=3):
        super().__init__(width = 3,height = 3)
        for x,y in enumerate(self.cells):
            print(x and y)

Hey, I'd recommend watching the end of the Emulating Built-ins video Kenneth explains it really well using iter(). But you're really close it's just that in the question they ask you to make all board instances iterable. So you'd need to define a new method for your Board Class called iter().

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))

    # Here is the code added            
    def __iter__(self):
        for cell in self.cells:
            yield cell

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

thanks for helping me!

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))

# Here is the code added            
def __iter__(self):
    for cell in self.cells:
        yield cell

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