Whats is going on? Make the cell atribute iterable

i can to understand whats is wrong in my code. I've already test it on jupter notebook and it works perfectly. I tested with this code:

ttt = TicTacToe()
ttt.cells

for _ in ttt.cells:
    print(_)
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))
    def __iter__(self):
        yield from self.cells             

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

  • You code worked when I copied and pasted it into the challenge, you can also do the following if it is still not working, it will still pass the challenge --> Give the __iter__ method to TicTacToe instead of giving it to Board. :star:

I think the code looks OK, and it works for me when I copy this as is, right into the challenge. It might be the fairly common issue of mixed tabs and spaces in the challenge editor. (Check your Jupyter setup - maybe it's using tabs instead of spaces?)

Usually when it has mixed tabs and spaces jupyter notebook shows an arrow to represent a tab. I had this problem, at first but i fixed and it didn't works. So now i did what @carlaos91 told (thanks, man), give the iter method to TicTacToe, and it finally work.

Thanks for answer me, Louise.

No problem.

It is also possible that what Louise said is the case here, usually, not only with the Treehouse challenge input fields but also in an outside python environment the accidental occurrence of extra tabs and spaces affect the execution of statements.

In the future, here on Treehouse and elsewhere you code always check to have no extra tabs between functions, classes, and functions of classes.

Happy coding. :star:
