Here is my code(I just add the related part):

………….. ##I didn't paste here because we have just definition of list
for triplet in itertools.product([0, 1], repeat=6):
    arr = np.array([])
    for i in range(8):
        for l in range(8):
            if l[l] == n[i]:
                arr = np.append(arr,[1])
                
            else:
                arr = np.append(arr,[0])
                
    print(arr)
