Python relies on proper indentation to know which code belongs inside a loop or function.
Create an empty list and use a loop to append 8 sub-lists, each containing eight zeros. 9.1.7 Checkerboard V2 Codehs
Use one loop to iterate through each row (0-7) and a nested loop to iterate through each column (0-7). Python relies on proper indentation to know which
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 The core of this challenge lies in understanding
Call the provided print_board function to display your final 2D list. Solution Code
Ensure both loops run exactly from range(8) to avoid errors when accessing the 8x8 grid.
Inside the nested loop, use the (row + col) % 2 logic to assign 1 to the correct positions using the syntax grid[row][col] = 1 .
