Referring to the same method as the previous question: suppose we call this

method on a linked list that described in your answer $($i$.$e$.$ a linked list that fails

to satisfy the docstring$).$

What kind of error would be raised when we call the method, and why?

class LinkedList:

def get$\_$fourth$\_$item$($self$)->$ Any:

$"""$Return the item stored at index $3.$

$($As with array$-$based lists, LinkedList indexing starts at $0.)$

$"""$

return self.$\_$first.next.next.next.item

TypeError, because the method returns a node instead of an item.

IndexError, because there does not exist an item stored at index $3.$

AttributeError, because 'NoneType' object has no attribute $[...]$

NameError, because the item at index $3$ is not defined.

KeyError, because there is no "key" stored at index $3.$
