[Python] Possible follow-up on arithmetic support

[AlenkaF]

Describe the enhancement requested

Basic arithmetic on arrays and scalars has been added here: #48085.

There are few things that we might work on as a follow-up in case there are requests/interest.

& / | operators and bool type

From #48085 (comment):

The & / | operators are currently mapped to the bitwise kernels, but in array-land, I think the most common use case for those is actually for logical (boolean) operations. So as a user, I would expect those to also work on bool type.

• Newly added & / | operators are not working on boolean arrays/scalars due to kernels only supporting integer types,
• Think about using logical kernels (pc.and_/pc.or_) if the input is bool.

Math-related dunder methods

We have moved math-related dunder methods out of the PR that added support for basic arithmetic:

• GH-32007: [Python] Support arithmetic on arrays and scalars #48085
• 72390ed
• b765549

These methods could also be supported if needed.

Hey, @AlenkaF !
If I remember correctly, the consensus was to let it be as is for the time being, and in case of any feature requests, we can switch to the other approach.

Could be! Or was that for the case of math-related dunders? (just opening an issue for that, so we have it tracked)

[AlenkaF]

Aha, I see the later comment:

We can keep the bitwise operators, remove the round/floor/etc. dunders, and perhaps improve things later if people request it.

which also deals with & / | operators, yes, correct.

Lets keep this open then, in case we might want to switch. I will update the issue description so it reflects it might be something we work on in the future.
