I have two lists:

```
l1 = [[1,2,3,4,5], [1,2,4,6,7]]
l2 = [[1,2,3,4,5], [1,2,4,6,7], [1,2,3,6,8], [1,2,3,0,9], [1,2,6,7,6]]

```

I want to create a new list `l3` that contains the items of `l2` that are not in `l1`. Something like this:

```
l3 = l2-l1

```

So, I am expecting an `l3` as:

```
l3 = [[1,2,3,6,8], [1,2,3,0,9], [1,2,6,7,6]]

```

How can I achieve that?
Any solution Using remove() or delete() in python..?
