What is the output of this code? I do not understand how the output is 8

Question

list = [1, 1, 2, 3, 5, 8, 13]
print(list[list[4]])

Answer 1

list[4] ---> 5
so:
list[5] ---> 8

Answer 2

The innermost set of brackets is checked first. That's:

list[4].

The value there is 5, so list[list[4]] equals:

list[5]

And that's 8.

Answer 3
