List/ Index- Why is this answer 8 and not 5, I'm new please explain.

Question

What is the output of this code?
list = [1, 1, 2, 3, 5, 8, 13]
print(list[list[4]])

Answer 1

Evaluate from inside -> list[4] first and list[list[4]] next.

list[4] = 5 meaning list[list[4]] = list[5] = 8.

Answer 2

list[list[4]]
list[4] = 5
list[5] = 8
