Modules are there to be used...

Here is one with itertools from the standard library that gets close:

input = "hello Python team".split()
result = []
for n in range(len(input):
   result += [item for item in it.combinations(input,n+1)]

If you really want to do it from scratch then Google combinations
algorithm, or look on wikipedia.
