Don't know how to use itemgetter without the list stating a kwarg

This quiz is asking me to use itemgetter in a way that was not covered in the lesson. I understand passing the keyword as the argument in itemgetter but am not aware of how to use it on a tuple. The only thing that seems to make sense in an index of each tuple but i cant really seem to get that to work.

sorting.py
from operator import itemgetter

fruit_list = [
    ('apple', 2),
    ('banana', 5),
    ('coconut', 1),
    ('durian', 3),
    ('elderberries', 4)
]

sorted_fruit = sorted(fruit_list, key=itemgetter(index[1]))

Running your code gives a NameError: name 'index' is not defined. Instead of key=itemgetter(index[1]), have you tried key=itemgetter(1)?

I actually happened to find that in docs.python shortly after I posted... And yes it worked like a charm!
