Help understanding answer in Python's Module 2 Quiz

Question

Hi all,

I'm having a little trouble understanding this.

"What is the output of this code?

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

I used 5 XP to find out that the answer is 8 but I'm stumped on why the answer is not 5.

Answer 1

first inner list is evaluated ,i.e. list[4] in list[list[4]]
which returns 5 ,

that 5 becomes index for the outer list
list[list[4]] is now treated as list[5] which in turn returns 8

Answer 2

Francis Larkin , list[4] => 5, then list[5] is 8, because you have list[list[4]].

Answer 3

There’s a bug in the code. Why?

message = "Debugging
print(message)
PY
the print statement is missing a parenthesis
the hash symbol is missing for the comment
the string value is missing a quotation mark
