In your first case, any positive index except 2 will work, For example: L = [0, 1, 2] L[::1], rest = "abcdef" # L became ['a'] or L[::3], rest = "abcdef" # L became ['a', 1, 2] I found iff when you change the length of L to 1(L[::3]) or didn't change L at all (L[::1], L[::]), this expression will work. But I'm not sure that is what you expected.
