To reverse a sequence, try the reversed operator to get the reverse iterator, then enumerate all the elements:

numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
for element in reversed(numbers):

I did some research and this can be achieved via slicing as well:

numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
for element in numbers[::-1]:

Now i found the website "learnpython.org", there was that slicing stuff. But I never knew'd about the "reversed" stuff. Thanks, again
