Why my python program returning different Output on every execution

Question

I have been doing a challenge to find a runner up score from a list
or
You can say I was trying to find the second largest from a list.

array = '57 57 -57 57'

print(list(set(sorted(array.split(' '))))[-2])

But on every execution the program returning different Output.

Why it is behaving like this??

A set is not an ordered data structure. I'm not really sure why you're using set at all - are you _supposed_ to be removing duplicates? — jonrsharpe, Oct 18 '21 at 09:01

Change it to this:

array = '57 57 -57 57'

print(list(sorted(set(array.split(' '))))[-2])

'set' doesn't preserve the order, so first get the set value and then sort it.

I guess, `list` now becomes redundant, because `sorted` already returns a list. – bereal Oct 18 '21 at 09:02
@bereal It is no longer needed to wrap the entire thing in list. – Kunal Tanwar Oct 18 '21 at 09:15

@KunalTanwar that's exactly what I said. – bereal Oct 18 '21 at 09:19
