Here's the code for the exercise on CodeHS:
In this article, we will break down exactly what the 9.1.6 Checkerboard v1 assignment asks for, how to approach the logic, and provide a fully commented solution.
In the CodeHS exercise , the goal is to create a checkerboard pattern using a 2D array. This specific version usually focuses on populating the grid with alternating values (like 0 and 1 ) to represent the two different colors of a board. Logic Breakdown
The outer loop handles rows, while the inner loop handles individual columns.

The assignment on CodeHS is a common hurdle for many intro Python students. While it looks like a simple grid, the goal is to master nested loops and 2D lists (lists of lists) by setting specific values to represent checker pieces. The Goal You need to create an 8x8 grid where: 1s represent checker pieces. 0s represent empty squares. The top 3 rows and bottom 3 rows should be filled with 1s. The middle 2 rows (rows 3 and 4) must remain as 0s. Step-by-Step Logic
To solve this, you need to understand two fundamental concepts:

: Avoid using explicit pixel numbers like 50 for the square size. If the canvas size changes, your board will break. Stick to the dynamic SQUARE_SIZE constant. To help adapt this to your project, could you let me know:
set canvas size (e.g., 400 x 400) set number of rows/cols = 8 square_size = canvas_width / 8
