V2 Codehs - 9.1.7 Checkerboard

It looks like you're asking for the solution or an explanation for the problem (Exercise 9.1.7) on CodeHS.

# Constants for the canvas dimensions CANVAS_WIDTH = 400 CANVAS_HEIGHT = 400 # Configuration for the checkerboard NUM_ROWS = 8 NUM_COLS = 8 # Calculate the size of each square dynamically SQUARE_SIZE = CANVAS_WIDTH / NUM_COLS def draw_board(): # Outer loop iterates through each row for r in range(NUM_ROWS): # Inner loop iterates through each column inside that row for c in range(NUM_COLS): # Calculate the top-left x and y coordinates for the current square x_pos = c * SQUARE_SIZE y_pos = r * SQUARE_SIZE # Create the square object rect = Rectangle(SQUARE_SIZE, SQUARE_SIZE) rect.set_position(x_pos, y_pos) # Determine color using the row + column parity logic if (r + c) % 2 == 0: rect.set_color(Color.black) else: rect.set_color(Color.red) # Add the completed square to the canvas add(rect) # Call the function to render the checkerboard draw_board() Use code with caution. Code Breakdown 1. Dynamic Sizing

For example, in a simple implementation: 9.1.7 Checkerboard V2 Codehs

Here is the correct Python code using the Turtle module to solve this problem.

Outputting the multi-dimensional structure cleanly via a custom function. It looks like you're asking for the solution

: You are managing a list where each element is itself a list (representing a row). Logical Strategy To solve this correctly, follow these general steps:

This article provides a comprehensive walkthrough for completing the exercise in CodeHS. This challenge builds upon basic looping concepts by introducing nested loops and conditional logic to create a complex visual pattern. Understanding the Objective Dynamic Sizing For example, in a simple implementation:

The final result is an 8x8 list of lists where every adjacent element (horizontally and vertically) alternates between 0 and 1. modulus operator works for other patterns, or should we look at a different CodeHS exercise
