other_key = set(data_dict.iterkeys()).difference([not_wanted]).pop() saves you the construction of an unnecessary set instance. At the cost of a bit more verbosity, you can get rid of a second set: key_set = set(data_dict.iterkeys()) key_set.difference_update([not_wanted_key]) other_key = key_set.pop() although the loss of clarity compared to the one liner can't be worth the miniscule benefit in this case. -- \S under construction -- http://mail.python.org/mailman/listinfo/python-list
