Please correct me if I’ve concluded it incorrectly.
For an empty list:
“any” is always False
“all” is always True
“none” is always True

Yep. It's the concept of vacuous truth

[Fabrizio Scarponi]

1. `any()`: Returns True if at least one element in the iterable is true. For an empty iterable, it returns False.
2. `all()`: Returns True if all elements in the iterable are true. For an empty iterable, it indeed returns True.
3. none is not a built-in function in Python Kotlin (since version 1.0). If you're referring to a function that would return True if no elements in an iterable are true (i.e., the opposite of any()
any(emptylist) -> false
all->true
none-> !any -> true

why mention Python? these are all Kotlin extension functions

the docs give examples on empty collections as well

On the off chance that that message was AI-generated, at least make sure you mention the language of interest in your prompt, and read over the message before you post it. There's nothing in the Kotlin Slack's rules against AI-generated anything, but just try to make it helpful

[ephemient]

this isn't in the rules but I would prefer a stronger statement: unless you can validate its accuracy, don't share AI-generated content. otherwise, you're not adding any value over the asker using the same tool themselves.

[Fabrizio Scarponi]

yea! this is a fast generate reply, where i removed a lot of useless information! now i will let it concern only kotlin...

[Youssef Shoaib [MOD]]

Yeah just try to be mindful of the contents of the response itself and how relevant it is. I'm all in favour of using AI as a communication aid and to speed up writing, as long as the content itself is still factual and relevant
