Pay attention, chief. I suggested this days ago to remove duplicates from a list. from itertools import * [ x for (x,s) in izip(iterable,repeat(set())) if (x not in s,s.add(x))[0] ] ;) There is a way to even avoid repeat if you're feeling EVIL. [ x for x in iterable if x not in locals()['_[1]'].__self__ ] Turning this into a turing machine is left as an exercise.
