To solve this, you first initialize an 8x8 grid of zeros. Then, use a nested loop to check if the sum of the row index and column index is odd or even to determine where to place the 1 s.

You need to create an 8x8 grid (a list of lists) where the elements alternate between 0 and 1 . The key constraint is often that you must use nested loops and assignment statements ( board[i][j] = 1 ) rather than just printing the expected output string.

: Many students try to print the pattern using a string like "0 1 0 1" . However, the CodeHS autograder often checks if you actually modified the list values. To solve this, you first initialize an 8x8 grid of zeros

: In Python, improper indentation of your nested loops will cause a SyntaxError or logic failure. Ensure your if statement is inside the second loop. The key constraint is often that you must
