9.1.6 Checkerboard V1 Codehs [upd] -

In CodeHS Exercise 9.1.6: Checkerboard, v1, the goal is to initialize an 8x8 grid where certain rows represent checker pieces (1s) and others represent blank squares (0s)

• If (row + column) is even, the square is usually Black.
• If (row + column) is odd, the square is usually White.

Algorithmic approach

Core observation: parity (even/odd) of row+column determines which symbol to place. 9.1.6 checkerboard v1 codehs

Here is a comprehensive breakdown of the logic, the code, and how to understand the underlying math. The Logic: Why a Checkerboard? In a standard In CodeHS Exercise 9

Circles overlapping? Ensure your position math uses (col * radius * 2). If you just use radius, they will all stack on top of each other. If (row + column) is even , the square is usually Black

: If you get a red mark saying "You should set some elements of your board to 1," ensure you are actually modifying or appending values to the list, not just printing text that looks like a grid. Function Placement : Always define your print_board function at the top of your script to avoid scope errors. for version 2 of this exercise?
