I can't figure this one out by myself. I need help, and I keep getting Bummer! Try again!
I don't know what I am doing.
import datetime birthdays = [ datetime.datetime(2012, 4, 29), datetime.datetime(2006, 8, 9), datetime.datetime(1978, 5, 16), datetime.datetime(1981, 8, 15), datetime.datetime(2001, 7, 4), datetime.datetime(1999, 12, 30) ] today = datetime.datetime.today() def is_over_13(datetime): return today.year*365 - datetime.year*365 >= 4745 def date_string(eday): return eday.strftime('%B %d') birth_dates = sorted( filter(date_string, map(is_over_13, birthdays)) )

Here is the code for the last part:
birth_dates = map(date_string, filter(is_over_13, birthdays))
First you will need to filter out the birthdays under 13 by using filter(). This will only return the truthy values. Then you can map all of these values returned for the date_string function.
