Now *this* sounds more useful to me: an itertool that generates *all* subsets
of a list. It's
quite easy to do with existing itertools, though, either by looping over the
second argument to
combinations, or (for a different ordering) using product:
def subsets(iterable):
l = list(iterable)
for selector in itertools.product([False, True], repeat=len(l)):
yield [element for indicator, element in zip(selector, l) if indicator]
