Python basics

Question

Hi there, I played this challenge and got this question:

s = set('solo')
s.add('learn')
print(s)

And the output is:

{'o', 'learn', 's', 'l'}

Can anyone explain this to me, please ?? :/

Answer 1

It makes a set from the word solo.
Because set items must be unique any duplicated letter will be deleted so only s, o and l letters will be added

Answer 2

Yes I see now, thank you for explaining.
