# Determine the color based on the sum of row and col indices # If the sum is even, it's one color; if odd, it's the other. if (row + col) % 2 == 0: square.set_color(Color.black) else: square.set_color(Color.white)

rect.setColor(Color.WHITE);

The ultimate goal is a board that looks something like this:

if ((row + col) % 2 == 0) square.setFillColor(Color.RED); else square.setFillColor(Color.BLACK);

After you've built a full row of 8 numbers, you append that row (as a list) to your main board list.

A loop that repeats the setup and move functions until the top of the world is reached. 3. The 9.1.6 Checkerboard V1 Code Solution
