subset generator

all_subsets.py

def all_subsets(*args):
  from collections import Iterable
  from itertools import permutations as permute
  if len(args) == 1:
    if not isinstance(args[0], Iterable):
      args = [args[0]]
    else:
      args = args[0]
  
  output = []
  for i in permute(args):
    output.append(i)
  
  return output

slightly improved to deal with any non-iterable object as well
