: The for row and for col loops ensure you check every "cell" in your grid.
def next_row(): turtle.penup() turtle.backward(400) turtle.right(90) turtle.forward(50) turtle.left(90) turtle.pendown()
if ((row + col) % 2 == 0)
: Do not just use print("1 1 1...") manually. The assignment tests your ability to access and replace values within a list. ✅ Final Result 916 checkerboard v1 codehs fixed
If you are looking for a solution, this comprehensive guide will break down the exact problem, the mathematical logic required, and the corrected Python code you need to pass the exercise. Understanding the Goal
# Constants SIZE = 50 # Size of one square ROWS = 8 COLS = 8
is , the cell gets the primary color (e.g., Black or true ). : The for row and for col loops
Here's a fixed solution to the 916 Checkerboard V1 CodeHS challenge:
If your original code was failing the CodeHS autograder, it likely suffered from one of three common architectural flaws: 1. The Ovens vs. Evens Row Problem
for row in range(8): # Start with a new empty row current_row = [] ✅ Final Result If you are looking for
public class Checkerboard extends ConsoleProgram public void run() // 1. Initialize a standard 8x8 2D array int[][] board = new int[8][8]; // 2. Use nested loops to traverse rows and columns for (int i = 0; i < board.length; i++) for (int j = 0; j < board[i].length; j++) // 3. Check if the sum of indices is even or odd if ((i + j) % 2 == 0) board[i][j] = 0; else board[i][j] = 1; // 4. Print the final grid layout printBoard(board); // Helper method to display the 2D array properly private void printBoard(int[][] array) for (int[] row : array) for (int element : row) System.out.print(element + " "); System.out.println(); Use code with caution.
