confusion with hashable

[spalisetty06]

Hi Sir, thank you for helping me out, am I very happy now, but for this.

'''tuple inside set'''
s = {(1, 2), (1, 2)}
print(s[0][1])

Output:
TypeError 'set' object is not subscriptable

I am good here, because with set, we can't predict the order, we may not use it

here is problem

''list inside set'''
s = {[1, 2, 3], [3, 4, 5]}
print(s[0])

Output:
TypeError: unhashable type: 'list'

here I am using set only, but I think, I should get the same output as ago, why is it complaining about list?
