Python relies on proper indentation to know which code belongs inside a loop or function.
To create a checkerboard, we use the row and column indices. If the sum of the and column index is even, we assign one value (e.g., 0); if it is odd, we assign the other (e.g., 1). This is easily checked using the modulo operator ( % ): if (row + col) % 2 == 0: (Sum is even) else: (Sum is odd) Step-by-Step Implementation 9.1.7 Checkerboard V2 Codehs
To solve the exercise, you need to create an 8x8 grid (a 2D list) and fill it with alternating 0s and 1s to form a checkerboard pattern. Python relies on proper indentation to know which
Inside the nested loop, use the (row + col) % 2 logic to assign 1 to the correct positions using the syntax grid[row][col] = 1 . This is easily checked using the modulo operator
The core of this challenge lies in understanding how to access specific elements in a list of lists and applying a mathematical condition to alternate values. The Core Logic: The Modulo Operator
