So, values() can't return a set because of (at least) the two reasons given above. And since, as Scott David Daniels pointed out, dicts support the iterator protocol, you can ask for a set of the keys easily enough if you want it: >>> d = dict(a=1, b=2, c=3) >>> set(d) set(['a', 'c', 'b']) So, IMHO, there's not much point to having keys() return a set.
