9.1.7 Checkerboard V2 Codehs ((new)) -
To build a checkerboard pattern efficiently, you do not need to keep track of a toggle variable that manually flips back and forth. Manual toggling often introduces bugs when switching to a new row. Instead, you can rely on the mathematical properties of coordinates.
This skill directly translates to drawing game boards (chess, checkers, tic-tac-toe), data visualizations, and tile-based maps.
Inside the inner loop, use an if-else statement combined with the modulo operator ( % 2 == 0 ) to determine if the current coordinate sum is even or odd. Conceptual Code Structure
When you run the code, you should see a perfect 8x8 checkerboard with alternating colors, no bleeding, no misalignment, and the first square of row 0 black, row 1 red/white, row 2 black, etc. 9.1.7 Checkerboard V2 Codehs

Here is a detailed review of why this code works and the specific concepts being tested.
Once my_grid is constructed, the final step is to pass it to the provided print_board function to visualize your work and complete the program: To build a checkerboard pattern efficiently, you do
:
A correct implementation will consistently produce an alternating pattern for any board size.
N = 8 squareSize = 50 setCanvasSize(N * squareSize, N * squareSize) This skill directly translates to drawing game boards
Here's the complete code for the 9.1.7 Checkerboard V2 Codehs problem:
What are you using? (e.g., Java, JavaScript, Python)
Your goal is to build the my_grid list that holds the checkerboard data. To do this efficiently, you'll use a list comprehension, which is a concise way to create a list by applying an expression to each item in an existing sequence. Here's how to break it down:
