This approach uses a nested loop as required by the CodeHS autograder.
# Draw the square no_stroke() rect(col * square_size, row * square_size, square_size, square_size) 916 checkerboard v1 codehs fixed
In CodeHS’s JavaScript graphics environment, you don't just print a pattern—you actually draw the board. The core logic remains the same, but you'll use graphics functions like Rect to create each square. The same (row + col) % 2 conditional is used to choose the color of each tile. This approach uses a nested loop as required
We import the turtle module to use graphics. The same (row + col) % 2 conditional
Toggling a boolean variable at the end of the inner loop without accounting for whether the row length is even or odd. If your grid width is an even number (like 8x8), toggling a boolean at the end of a row makes the next row start on the exact same color.
