i'm getting the same error message as ajaxrunner15120
as far as i can see the code looks correct, and i tried it in firefox as well. could there be something wrong with the terminal?
board =  for x in range(5): board.append(["O"] * 5) def print_board(board): for row in board: print " ".join(row) print_board(board)
any help would be greatly appreciated.
