Um, everything is fine, but there is a sentence that says we've created two-dimensional list.
Now, I want to ask you something, since I realized that that list is actually not two-dimensional, just printed
to look that way.
Do you really create two-dimensional list just by printing the code below?
Is that even two-dimensional list, or just looks like that?
If not, could you tell me how to create two-dimensional list?
board =  for x in range(0, 5): board.append(["O"] * 5) def print_board(board): for row in board: print " ".join(row)
