Use sorted() and attrgetter() to sort date_list by the day attribute of each datetime object. Save this sorting into a variable named sorted_dates

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(datetime.datetime, key=attrgetter('day'))

You have the right idea, but the first argument to "sorted" must be the thing that you are going to sort, which in this case is the "date_list":

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