don't know. just wanted to do it with the least amount of code i could, mainly time's sake

i feel like thats the best way to learn lol, at least imo.

I believe best practice is a combination for shorter lines of code as well as readability. I've seen some solutions here that are extremely short but also extremely unreadable. I mean, it's Python we're doing here not Java or something😅

(This is a joke!!)

this is clever. it is more also obtuse. a more senior dev might look at this and immediately know what's going on, but a junior dev might not. it is not a best practice

Speaking about best practice. I think in this case it's not about one-liner or readability, but more about code duplication.
I suppose that best practice is keeping in mind maintainability and requirements changing during writing the code.

So here when someone would ask to change greeting from 'Hello' to 'Good gay' or add '!' to the end of the sentence - you will need to change it twice.
It's not a big deal here, but with more lines of code it would matter more. But good habits stem from the very beginning:)

I personally agree with you. And I think that's exactly why Codewars differed 'clever' from 'best practices'. But sadly mostly people just ignore the 'Clever' button. Or they just simply has a different view of what is best.

Honestly I dont think there is a universal answer.
However, in my mind, a good software engineer writes cohesive and linear code- length is not a factor.

Just for showing off superiority, we as noobs need to bow. :^)

it usually doens't matter , people usually do it for fun , doing one liners however is not a good practice always but the satisfaction is real

Serious question here, does "best practice" value smaller lines of code than readability? I think the code in the submission below this one is more readable; therefore, is a best practice. Someone please enlighten me.

a set is a data structure that can contain no duplicate elements.
