916 Checkerboard V1 CodeHS Fixed
The 916 Checkerboard V1 problem on CodeHS is a popular challenge that requires students to create a checkerboard pattern using code. Here is a fixed solution to the problem:
- Outer Loop (
for i in range(ROWS)): Controls the vertical drawing. It runs 8 times (once for each row). - Inner Loop (
for j in range(COLS)): Controls the horizontal drawing. It runs 8 times for every single row (totaling 64 squares).
CodeHS 9.1.6 Checkerboard v1: FIXED & WORKING! Struggling with the logic for the Checkerboard problem in Python? I finally got the 916 checkerboard v1 codehs fixed
To fix the CodeHS 9.1.6: Checkerboard, v1 assignment, you must ensure you are not just printing the final output, but actually modifying the elements of a 2D list (grid) using assignment statements. The autograder specifically checks for code that sets elements to 1. Fixed Python Code 916 Checkerboard V1 CodeHS Fixed The 916 Checkerboard
version passing all test cases! The key was properly nesting the loops and using the modulo operator to toggle the colors based on the row and column index. What was fixed: Corrected the row/column offset logic. Ensured the pen colors switch perfectly every other square. Fixed the positioning so the board starts exactly at the corner. The Logic: (row + col) % 2 == 0 Outer Loop ( for i in range(ROWS) ):
Now, loop through the rows and columns. According to the instructions, you need 1s in the top three rows (indices 0, 1, 2) and the bottom three rows (indices 5, 6, 7). To get that alternating checkerboard look, use the modulus operator
