Now ,create a variable silly_list
messy_list = [5, 2, 1, 3, 4, 7, 8, 0, 9, -1]
# Your code goes below here
clean_list = messy_list[:]
clean_list.sort()
silly_list = clean_list[8:-1:-3]

15,720 PointsYour're close. Say we have a list of ints [0, 1, 2, 3, 4, 5, 6, 7, 8]; your code is telling python to start at the 8th index, which gives us the last item in the list (8 in this example). Your code also tells us to stop at -1, which also gives us the last item in the list, which is 8 again.
Try telling python to start with a negative index and don't forget that slices have defaults. [1 : : 3] would start at 1 and go to the end (length) of the list and give us every third item.

Treehouse Guest TeacherIan Keith's answer is a great one but you did find a mistake in the code challenge. I had messy_list in the error message where I should have had silly_list. Thanks for finding that!

Your code goes below here
clean_list = messy_list[:] clean_list.sort() messy_list = clean_list[10:-3]
