After implementing the code above, run the program. You should see:

If the board starts with black instead of red, simply swap the colors in the if-else block.

We import the turtle module to use graphics.

The checkerboard problem isn’t just about drawing a pretty pattern. It teaches: After implementing the code above, run the program

Getting the "916 checkerboard v1 codehs fixed" means you’ve mastered these core programming concepts.

Before we jump to the "fixed" code, let’s break down the assignment’s requirements:

The most common "non-fixed" issues students encounter: If the board starts with black instead of

You are tasked with creating a checkerboard pattern using a grid of squares. The board should have 8 rows and 8 columns of alternating black and red squares. The top-left square should be red.

This is "v1" of the problem, meaning it likely expects a straightforward approach using nested loops and conditionals, without more advanced optimizations.
