The autograder often checks if you actually changed the values in the list using my_grid[row][col] = 1 . Simply printing a pattern without updating the list will likely cause the test to fail.
Python relies on proper indentation to know which code belongs inside a loop or function. 9.1.7 Checkerboard V2 Codehs
Create an empty list and use a loop to append 8 sub-lists, each containing eight zeros. The autograder often checks if you actually changed
Use one loop to iterate through each row (0-7) and a nested loop to iterate through each column (0-7). 9.1.7 Checkerboard V2 Codehs
Inside the nested loop, use the (row + col) % 2 logic to assign 1 to the correct positions using the syntax grid[row][col] = 1 .
