How can I display queryset values by x in group?

```
qs = Item.objects.all() # 12 items
count = len(qs)

if count > 5:
    for item in qs[:5]:
        print item
    # now I need to display the rest(next 5 items and later 2 items) of results.
    # something like this: for item in qs[5:10] and next for item in qs[10:12] 
    # BUT I don't know how many items will be in queryset. This is only example.

```
