What's the usage of print(list[list[int]])

Question

While going through the question for Python, I have seen a question with the following code:

CODE:

list = [1, 2, 3, 4, 5, 6]

print(list[list[1]])

OUTPUT :
3

I have tried it, and tried to understand it but I don't get it.
Can someone explain please ?

Answer 1

You have start with the inner most [ ] :
list[1] - > the item on index 1 is the value 2
So list[1] = 2
The next one is then
list[2] - > gives the value on index 2, which is the value 3
That's all.

Answer 2

Check the list from inside first, list[1].
list[1] is 2. So list[list[1]] is list[2].
list[2] is 3.

list[list[1]] == list[2] == 3
