The left operand determines the result. The manual specifies that < and > do not have to be consistent. But I suspect that when 3.x dict.keys() was backported to 2.7.0, no one thought to update set, whereas the backported key view code already had the comparison.
The question is why set() is raising an exception instead of returning NotImplemented to give the other operand a chance. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
