Oops! The dictionary iterates over keys, not values as I stated (and
demonstrated by your working code). Consequently, the example I gave could
be more succinctly expressed by:
sa = set(a)
sb = set(b)
Sorry for the error.

You should iterate over the keys of the dictionary:
for k in a.keys():
because if you iterate over the full dictionary, your items are the values,
not the keys. Otherwise your code looks correct, and I don't think its
terribly bad form. You could do something interesting with sets:
sa = set(a.k
