10,307 PointsFiguring the POSIX timestamp challenge out, getting NoneType error when trying to unpack a tuple of args into a list
I am getting a list of arguments with def my_func(*args):
I've tried:
def my_func(*args):
posixes = []
for i in args:
posixes.append(i)
I've also tried:
def my_func(*args):
posixes = list(args)
Please help! :)

10,307 PointsHere is the full code I currently have:
def timestamp_oldest(*args):
posix_list = list(args)
posix_list = posix_list.sort()
oldest = posix_list[len(posix_list)-1]
return datetime.datetime.fromtimestamp(oldest)

Treehouse Moderator 68,423 PointsAlexander, You are so very close. Remember POSIX time is an value that gets larger as time passes. So the oldest date would have the lowest number. Therefore you want posix_list[0]:
oldest = posix_list[0]
Here is my full solution for Task 1:
import datetime
def timestamp_oldest(*args):
lst = list(args)
lst.sort()
return datetime.datetime.fromtimestamp(lst[0])

10,307 PointsI am sorry for the poor markdown usage with code, but hopefully you get the gist of it.
