I'm not sure why [:0], would ever be useful -- it always returns an empty list, right? Did you mean [:1] ? But anyway, the behaviour here is exactly consistent with python lists: >>> [][0] Traceback (most recent call last): File "<stdin>", line 1, in <module> IndexError: list index out of range >>> [][:0] [] >>> [][:1] [] We are not helping newbies by making slicing for QuerySets work differently -- in fact we've gone to some length to make sure it behaves as analogously as possible -- it throws the same exceptions etc. Luke -- "My capacity for happiness you could fit into a matchbox without taking out the matches first."
