Getting the subsets of a set in Python

Question

Suppose we need to write a function that gives the list of all the subsets of a set. The function and the doctest is given below. And we need to complete the whole definitio

Answer 1

The usual implementation of powerset on list goes something like this:

def powerset(elements):
    if len(elements) > 0:
        head = elements[0]
        for tail in powerset(elements[1:]):
            yield [head] + tail
            yield tail
    else:
        yield []

Just needs a little bit of adaptation to deal with set.
