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

February 11, 2022Python: why can't I do reversedList = thisList.reverse() in one line? It outputs None and I'm not sure why.
Functions take inputs and return values. For example, len(something) takes as input something and returns a number. Because it returns a number, x = len(something) will set x to whatever len() returned. The reverse() function returns None. That's it, just None. Calling it changes the list that you call it on, but the function itself doesn't return anything. The reason it returns None is that you, as the caller, need to be made aware that you are not creating a new list: you're changing the original list. originalList.reverse() CHANGES the original list into the reversed list, so assigning the result of that change somewhere suggests that the programmer doesn't know this and is probably about to make a mistake. On the other hand, there's a different, built-in function with a very similar name: reversed(). That function takes as input a list and returns a new list that is reversed. You can use it like this: reversedList = reversed(thisList). This will not change thisList. There's a related important concept here around what's called "side effects." Some functions change the state of the other things, and some functions simply calculate a value from inputs without changing anything. Functions that change things are said to have "side effects," and functions that do nothing besides returning a value, and always return the same value for the same input, are called "pure" functions. reversed() is a pure function, and someList.reverse() has side effects.

List can be reversed using for loop as follows:
>>> def reverse_list(nums):
... # Traverse [n-1, -1) , in the opposite direction.
... for i in range(len(nums)-1, -1, -1):
... yield nums[i]
...
>>>
>>> print list(reverse_list([1,2,3,4,5,6,7]))
[7, 6, 5, 4, 3, 2, 1]
>>>

8 Ways To Reverse The Elements In A Python List | by Sachin Pal | Medium
November 25, 2022 - Python reversed() function is also used to reverse the elements inside the list. Still, instead of returning the reversed object, it returns the reversed iterator object that accesses the values of a given sequence. To access the values, you have to iterate them either by using the for loop or the next() function...

November 7, 2025 - Slicing with [::-1] is suitable for small to moderate-sized lists where readability is important, despite its higher memory usage. Opt for loop-based reversal if you need to perform custom operations during the reversal process. It may be rather challenging to reverse a list in Python because of the following issues.

Use the built-in reversed() function:
>>> a = ["foo", "bar", "baz"]
>>> for i in reversed(a):
... print(i)
...
baz
bar
foo
To also access the original index, use enumerate() on your list before passing it to reversed():
>>> for i, e in reversed(list(enumerate(a))):
... print(i, e)
...
2 baz
1 bar
0 foo
Since enumerate() returns a generator and generators can't be reversed, you need to convert it to a list first.

You can do:
for item in my_list[::-1]:
print item
(Or whatever you want to do in the for loop.)
The [::-1] slice reverses the list in the for loop (but won't actually modify your list "permanently").

r/learnprogramming on Reddit: Reversing a list in Python?
February 11, 2022 -
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.
