CodeHS exercise 9.1.6 (v1) requires creating an 8x8 2D list and using nested loops with assignment statements to place pieces (1s) in the top three (rows 0-2) and bottom three (rows 5-7) rows. The solution involves initializing a grid of zeros, applying conditional logic to update specific elements, and printing the formatted grid. For a detailed breakdown of the solution, refer to the discussion on Reddit [Link: Reddit user thread https://www.reddit.com/r/codehs/comments/kt28qe/916_checkerboard_v1_answers_needed_what_am_i/].
Start by creating an 8x8 grid filled entirely with zeros. This serves as your blank canvas before "placing" the checker pieces.

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

In the CodeHS 9.1.6: Checkerboard, v1 exercise, the objective is to create an 8x8 grid where the top three and bottom three rows contain alternating 1s and 0s (representing checker pieces), while the middle two rows consist entirely of 0s. The final result should look like this:
