combination of elements

For combinations of two pairs: lambda l: [ (a, b) for i, a in enumerate (l) for b in l [i+1:]] And, for combinations of three pairs, it's as easy as this: lambda l: [ (a, b, c) for i, a in enumerate (l) for ii, b in enumerate (l [i+1:]) for c in l [i+ii+2:]] The result is identical to using itertools.combinations:

Another way to think about it, is whenever we add a new element to the set, it must cause the number of possible subsets of that set to double in size. Think about it: All the previous possible subsets are still possible, but now we can create a copy of each of them that contains the new element - in doing so we double the number of possible subsets
