maybe that thing in python 3 that someone mentioned is the answer, but otherwise i always think Python should admit something like this:
a, b, c, *d = list i.e. if list were [1,2,3,4,5], you'd get a=1, b=2, c=3, d=[4, 5] not that that solves the None problem, though i don't have any feature suggestions that would address that.
