SyntaxError with (tile.format('_'), end=' ') in Python 3.5.0

Hi guys,

When I try to run the code in the workspace console, I keep getting an SyntaxError specifically pointing to the '=' in (tile.format('_'), end=' ')

I looked around the community and there was a similar problem, but it was related to Python 2.

Any help?

That snippet is a bit to small to analyse. Could you post the whole code?
Or even better, make a snapshot of your workspace and post the link to it.

Haven't you forget "print" there ?

    for idx, cell in enumerate(CELLS):
        if idx in [0, 1, 3, 4, 6, 7]:
            if cell == player:
                print(tile.format('X'), end=' ')
            else:
                (tile.format('_'), end=' ')  # HERE

Also, you may not wanna put those spaces which will break your squares.
