How to sort a list of lists by a specific index of the inner list?

Question

I have a list of lists. For example,

[
[0,1,\'f\'],
[4,2,\'t\'],
[9,4,\'afsd\']
]

If I wanted to sort the outer list by the string field o

Answer 1

**old_list = [[0,1,'f'], [4,2,'t'],[9,4,'afsd']]
    #let's assume we want to sort lists by last value ( old_list[2] )
    new_list = sorted(old_list, key=lambda x: x[2])**

correct me if i'm wrong but isnt the 'x[2]' calling the 3rd item in the list, not the 3rd item in the nested list? should it be x[2][2]?
