Using one common definition of "combinations": >>> from pprint import pprint >>> pprint(items) [['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'N', 'P', 'S', 'C'], ['I', 'N', 'P', 'S', 'C'], ['F', 'I', 'L', 'O', 'N', 'P', 'S', 'R', 'C'], ['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'O', 'N', 'P', 'S', 'C'], ['F', 'I', 'L', 'O', 'N', 'P', 'S', 'R', 'C']] >>> import itertools >>> for c in itertools.combinations(items, 2): ... print c ... (['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'O', 'N', 'P', 'S', 'C']) (['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'O', 'N', 'P', 'S', 'C']) (['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'N', 'P', 'S', 'C']) (['I', 'O', 'N', 'P', 'S', 'C'], ['I', 'N', 'P', 'S', 'C']) <snip> If you mean something else (likely) please give a more detailed description or provide some examples with both input and desired output.
