Python is strict about spacing. Ensure your if statement is inside the second loop, and the second loop is inside the first.
The outer loop for r in range(NUM_ROWS): starts at row 0. Before moving to row 1, it hands control to the inner loop for c in range(NUM_COLS): . The inner loop runs completely across all columns. This means the program draws the board left-to-right, top-to-bottom. 3. Coordinate Positioning 9.1.7 Checkerboard V2 Codehs
: (row + col) % 2 == 0 checks if the sum is even → one color; odd → other color. Python is strict about spacing
But wait — V2 often wants you to , not row+col. Before moving to row 1, it hands control
) is even or odd. If the sum is even, use Color A; if odd, use Color B. Step-by-Step Implementation 1. Define Constants
You are tasked with creating a program that draws a checkerboard pattern. The board consists of alternating colored squares (e.g., red and black, or blue and white). The "V2" specification typically adds one or more of the following constraints:
To create an efficient solution, you need to identify the mathematical pattern.
