916 Checkerboard V1 Codehs Fixed Jun 2026

The pieces appear crooked or do not tile correctly.

Double-check your specific assignment prompt. Does CodeHS want true on even coordinates or odd coordinates? If your pattern is inverted, simply swap the true and false assignments in the if-else block.

: Ensure you initialize board = [] before the loops and row = [] inside the first loop. Index Management : Always use range(8) for an board to avoid "index out of bounds" errors. 916 checkerboard v1 codehs fixed

The core objective of CodeHS is to practice modifying 2D lists using nested loops and index-based assignment.

This part builds the checkerboard pattern. The pieces appear crooked or do not tile correctly

: Always use (row + col) % 2 == 0 pattern. Never rely solely on row or column index individually. If starting with a different color, adjust the condition accordingly.

A truly "fixed" solution will pass all CodeHS test cases, including: If your pattern is inverted, simply swap the

Define a function that iterates through each row of your 2D list. Use a list comprehension to convert the integers to strings so they can be joined by spaces for the final display. 4. Avoid Common Errors

The following code represents the "Fixed" solution. It uses a for loop structure which inherently handles the counting, solving the "infinite loop" bug often associated with while loops in this unit.

# Add the row to the board board.append(current_row)

To solve this correctly, you must use nested for loops and a mathematical check to determine which number (0 or 1) to place in each cell.
