I tryed the slicing stuff in python, but something went wrong

Question

Hi! can somebody check the code and tell me what's wrong? https://onlinegdb.com/_U1B8WPaZ .

i wanted the program to print the list backwards, 9 to 0. And there is no problem, it just wont print anything

Answer 1

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):
    print(element)

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]:
    print(element)

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