This question is confusing, and it gives a generic "Bummer! Try again!"

Ill link to my post to the previous challenge: https://teamtreehouse.com/community/i-am-completely-stumped-and-its-saying-task-1-isnt-passing

I don't get the concept of this functional programming biz at all. i don't know what to pass in to attrgetter!!

i've tried "date", "datetime.datetime.date", date, and many others!!

Thanks for your help, in advance. James.

sorting.py 
import datetime
from operator import attrgetter

date_list = [
    datetime.datetime(2015, 4, 29, 10, 15, 39),
    datetime.datetime(2006, 8, 15, 14, 59, 2),
    datetime.datetime(1981, 5, 16, 2, 10, 42),
    datetime.datetime(2012, 8, 9, 14, 59, 2),
]

sorted_dates = sorted(date_list, key=attrgetter("datetime.datetime.date"))

So the datetime is presented as year, month, day, hour, minute, and second. In that order. The biggest hint here is in the instructions where they ask you to sort by day. Take a look at the line you need:

sorted_dates = sorted(date_list, key=attrgetter("day"))
