Group List Elements according to the Input with the order of binary combination

I'm not sure where the variables are coming from, but you can pass them into itertools.product to get the list that you want from them.

>>> from itertools import product
>>> list(product(("a","ap"), ("b", "bp"), ("c", "cp")))
[('a', 'b', 'c'), ('a', 'b', 'cp'), ('a', 'bp', 'c'), ('a', 'bp', 'cp'), ('ap', 'b', 'c'), ('ap', 'b', 'cp'), ('ap', 'bp', 'c'), ('ap', 'bp', 'cp')]
