breaking appended list into indexes

Vote count:

0

So right now i have code that gives me

[-1], [1], [-1], [-1], [2], [3], [4], [-1], [5], [6], [7], [-1], [-1], [-1], [8], [9], [-1], [-1], [-1], [10]]

but i want it to look like so

myVV = [[-1, 1, -1, -1],[ 2, 3, 4, -1],[5, 6, 7, -1],[-1, -1, 8, 9],[ -1, -1, -1, 10]]

i have a for loop with a inserted line

myVV.append([])

that gives me this

[[], [-1], [1], [-1], [-1], [], [2], [3], [4], [-1], [], [5], [6], [7], [-1], [], [-1], [-1], [8], [9], [], [-1], [-1], [-1], [10]]

it inserts the break were i want the split of indexes to happen.

Any things to read that would help me solve this?
