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/].
: Create an empty list called board and fill it with eight rows of eight zeros.
The trick to the checkerboard pattern is checking the sum of the indices If the sum is , the square should be 0 . 9.1.6 checkerboard v1 codehs
The canvas is 400×400, but squares don't align perfectly. Fix: Calculate the window size dynamically from the square size and number of squares, as shown in the constants above.
: Within nested loops, check if the current row index is part of the top three (indices 0–2) or bottom three (indices 5–7). If so, change the 0 to a 1 using an assignment statement like board[i][j] = 1 . Step-by-Step Implementation CodeHS exercise 9
. This specific version focuses on the foundational step of creating a 2D structure where values represent different game states: for a checker piece and for an empty square. The Assignment Objective The goal is to create an
Here is a comprehensive breakdown of how to approach the code, the logic behind it, and the final implementation. : Create an empty list called board and
This pattern creates the diagonal "stepping stone" look of a checkerboard. 3. Grid Management
