in python def powerset s n len s masks 1 j for j in xrange n for i in xrange 2 n yield s j for j in range n if masks j.. powerset s n len s masks 1 j for j in xrange n for i in xrange 2 n yield s j for j in range n if masks j i if __name__ '__main__'.. is the empty set. Change the iteration from this for i in xrange 2 n to this for i in xrange 1 2 n if you want to skip an empty..
