Are you sure that's what you want? I'd expect [()] here (on the basis that the empty product is a one-element set). And indeed that's what itertools.product gives: >>> import itertools >>> list(itertools.product()) [()] > foofunction([1, 2, 3]) > # returns [ (1), (2), (3) ] Presumably you mean [(1,), (2,), (3,)] here?
