I wondered what was the recommended/prefered way of working with sets, for example a.difference(b) vs a - b, as in the first method it is clear we are working with sets, in the second not. However, the union operator is |, which isn't used for anything else.

PEP-218, which proposed the addition of sets, does not make any spcecific recommendation. Use your own judgement. – Barmar Jun 06 '20 at 17:32
