2.19.6: Checkerboard (python) Write a program that will draw a red and black checkerboard on the canvas. Squares should have side lengths of 40 pixels. They should alternate between black and red and each row should start with a different color. Hints: - You should use a variable called color_value to control the color of each square. - The Bubble Wrap program might be a good place to start. You can find it here!
