To get a new reversed list, apply the reversed function and collect the items into a list:
>>> xs = [0, 10, 20, 40]
>>> list(reversed(xs))
[40, 20, 10, 0]
To iterate backwards through a list:
>>> xs = [0, 10, 20, 40]
>>> for x in reversed(xs):
... print(x)
40
20
10
0

Reverse an Array in Python – 10 Examples - AskPython
April 14, 2026 - Python gives you multiple ways to reverse arrays, and the right choice depends on your data type and whether you need to preserve the original. For quick in-place reversal of a list, use list.reverse(). For a reversed copy without touching the original, slicing [::-1] is clean and idiomatic.

Hey, I'm learning lists in Python. When I try to use the reverse method to reverse my list it returns 'None'. I've read online that apparently this is because it doesn't actually change the list but I'm not sure what that means tbh. Even if it was a temporary modification, wouldn't it print that temporarily modified version of the list instead of printing 'None'? I found another solution (assuming the list is stored in my_list variable), print(my_list[::-1]). I understand that the -1 is referring to the end of the list (and maybe telling it to count back from there), but I have no idea what the '::' means. Would appreciate some help, thanks.

The way lists go in python is list[start_index:end_index:step]. By skipping the any of them they default to start_of_list:end_of_list:1. By doing ::-1, you're telling to go from the start of the list till the end by increasing the index by -1.

June 28, 2023 - Now, how can you reverse a list in place by hand? A common technique is to loop through the first half of it while swapping each element with its mirror counterpart on the second half of the list. Python provides zero-based positive indices to walk sequences from left to right.

There are three methods you can use to reverse a list:
-
An in-place reverse, using the built-in reverse method that every list has natively
-
Using list slicing with a negative step size, resulting in a new list
-
Create a reverse iterator, with the reversed() function
