https://py.checkio.org/search/?q=set.union gives... nothing but it probably should, right? Or not I do not care.

https://py.checkio.org/search/?q=union+user%3APhil15 gives things where I use "set.union".

Looking my practice (or see screenshot), it says I never used "set.union".

What's true for "union" is also true for "intersection".

Then there is "set.issuperset" twice on practice page ^^ like this was super important but it is not. It is just "a >= b" for sets, which I probably did unless I only do "a <= b".

Maybe I'm gonna be stuck at senior stage until I'm a real boomer ^^
