    def getBlankPosition(board):
        # Return the x and y of board coordinates of the blank space.
        for x in range(BOARDWIDTH):
            for y in range(BOARDHEIGHT):
                if board[x][y] == BLANK:
                    return (x, y)
    

    Whenever our code needs to find the XY coordinates of the blank space, instead of keeping track of where the blank space is after each slide, we can just create a function that goes through the entire board and finds the blank space coordinates. The None value is used in the board data structure to represent the blank space. The code in getBlankPosition() simply uses nested for loops to find which space on the board is the blank space.
