OrderedSet is most likely on the way, but for now Python 3.1 and 2.7 have OrderedDict. For 3.0 and 2.6 the recipe is here: http://code.activestate.com/recipes/576669 With OrderedDict you can do: OrderedDict.fromkeys(x).keys() # Returns an iterator in 3.x, a list in 2.x. -- http://mail.python.org/mailman/listinfo/python-list
