Ensure both loops run exactly from range(8) to avoid errors when accessing the 8x8 grid.
The goal is to generate an 8x8 grid where elements alternate. In computer science, this is a classic application of the . Grid Structure: A list of lists (8 rows, 8 columns). 9.1.7 Checkerboard V2 Codehs
: A common expert strategy is to check if the sum of the current row index and column index is even or odd. (row + col) % 2 == 0 , set the value to 1. Otherwise, keep it as 0. Assignment Requirement autograder often strictly requires you to use an assignment statement board[i][j] = 1 ) rather than just printing the pattern directly.
