The 9.1.6 Checkerboard v1 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
In "Checkerboard v1", the standard logic is to determine the color of a square based on the sum of its row and column indices. 9.1.6 checkerboard v1 codehs
var rect = new Rectangle(size, size);rect.setPosition(x, y);rect.setColor(color);add(rect);The most efficient way to determine the color of a square at position (row, col) is to check if the sum of the row and column indices is even or odd. Even sum (row + col % 2 == 0): One color (e.g., 0). Odd sum (row + col % 2 != 0): The other color (e.g., 1). Implementation Steps The 9
Output:
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.
