916 Checkerboard V1 Codehs Fixed New! Instant
The core objective of CodeHS 9.1.6: Checkerboard, v1 is to practice modifying 2D lists using nested loops and index-based assignment.
Typical Goal of "916 Checkerboard v1" (CodeHS)
You’re usually asked to create a checkerboard pattern (alternating black and red squares) using a graphics library (like graphics.py or JavaScript’s Graphics in CodeHS). 916 checkerboard v1 codehs fixed
# Constants
SIZE = 50 # Size of one square
ROWS = 8
COLS = 8
# Starting coordinates
x = -200
y = 200
- Row 0, Col 0: Sum is 0. Even $\rightarrow$ Black.
- Row 0, Col 1: Sum is 1. Odd $\rightarrow$ Red.
- Row 1, Col 0: Sum is 1. Odd $\rightarrow$ Red.
- Row 1, Col 1: Sum is 2. Even $\rightarrow$ Black.
This creates the staggered pattern required for a checkerboard.
