lists, strings, and byte strings

[Skaperen]

right, iterating over bytes or a bytearray gets a list of ints. and doing so over a string gets a list of strings that are each len() == 1. either of these is easy enough to do and it is easy enough for the same code to do it. but reversing it back is harder, and doing it with the same code is even harder, still. it's the reversing step i want to do. one ambiguity is bytes vs bytearray in python3. given a list of ints, you don't know which to go back to. i'll accept bytearray because it is available in both python2 and python3. btw, the code i seek that can reverse a list back to a string or bytearray, i want it to be the same code working in both python2 and python3 ... python version agnostic code.
