.sort() is only stable-sort if key is specified

@kyle

introducing the key it makes it explicit like not to check the second or the nth item in the tuple

Yes, exactly. If you don’t provide a key, the entire tuple is used for comparison. If you provide a key, only what’s in the key is used.

@shantanuojha

many websites say that it only compares the first element that’s where i got this doubt from.

Then those web sites are wrong Can you link to them? Maybe they can be edited.
