Is there a more elegant way to express ((x == a and y == b) or (x == b and y == a))?

Question

I'm trying to evaluate ((x == a and y == b) or (x == b and y == a)) in Python, but it seems a bit verbose. Is there a more elegant way?

Answer 1

If the elements are hashable, you could use sets:

{a, b} == {y, x}
