"It’s a coordinate problem," Maya corrected gently. "Think of a coordinate plane. You have an X and a Y. The color of a square depends on the sum of its coordinates."

If your automated grader is rejecting your code, check for these frequent pitfalls: "Think of a coordinate plane
From known coding assignments (e.g., CodeHS Python), "9.1.7 checkerboard v2" often adds:
If you need a more visual approach, some users find success by creating two distinct lists—one for odd rows and one for even rows—and printing them alternately 1.2.4 . However, the modulo math method shown above is more concise and generally considered the standard answer for this exercise.
If your 9.1.7 exercise utilizes a graphical canvas or grid-world (like Karel the Dog), the logic translates to moving, checking positions, and placing colored squares: javascript Copied to clipboard "It’s offset," Leo muttered, burying
This article provides a full breakdown of the problem, the logic behind the solution, the correct code answer, common mistakes, and how to truly understand the concepts so you can pass the autograder on the first try.
The first step is to create an empty list, often called my_grid , which will hold the rows of your checkerboard. Since a checkerboard is typically
# Create an 8x8 grid of 0s grid = [[0 for _ in range(8)] for _ in range(8)] # Use nested loops to apply the pattern for row in range(8): for col in range(8): # If the sum of row and column is even, set to 1 if (row + col) % 2 == 0: grid[row][col] = 1 # Print the final board print_board(grid) Use code with caution.

and use a loop to append eight sub-lists, each containing eight zeros, to establish the structure. 2. Implement alternating logic Use nested
