    ALLCOLORS = (RED, GREEN, BLUE, YELLOW, ORANGE, PURPLE, CYAN)
    ALLSHAPES = (DONUT, SQUARE, DIAMOND, LINES, OVAL)
    assert len(ALLCOLORS) * len(ALLSHAPES) * 2 >= BOARDWIDTH * BOARDHEIGHT, "Board is too big for the number of shapes/colors defined."
    

    In order for our game program to be able to create icons of every possible color and shape combination, we need to make a tuple that holds all of these values. There is also another assertion on line 3 [46] to make sure that there are enough color/shape combinations for the size of the board we have. If there isn’t, then the program will crash on line 3 [46] and we will know that we either have to add more colors and shapes, or make the board width and height smaller. With 7 colors and 5 shapes, we can make 35 (that is, 7 x 5) different icons. And because we’ll have a pair of each icon, that means we can have a board with up to 70 (that is, 35 x 2, or 7 x 5 x 2) spaces.
