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

Python · a = [1, 2, 3, 4, 5] rev = list(reversed(a)) print(rev) Output · [5, 4, 3, 2, 1] If we want to reverse a list manually, we can use a loop (for loop) to build a new reversed list.

How to Reverse a List in Python (Using 3 Simple Ways) | Cherry Servers
November 7, 2025 - This approach mixes Python syntax with the logic of a loop. Loop-based reversal follows a simple logic. Simply begin at the last item in the list and work your way backwards while collecting each element to create a new list.

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").

I would say to make the while loop act like a for loop.
firstList = [1,2,3]
secondList=[]
counter = len(firstList)-1
while counter >= 0:
secondList.append(firstList[counter])
counter -= 1

The simplest way would be:
def while_version(items):
new_list = []
while items: # i.e. until it's an empty list
new_list.append(items.pop(-1))
return new_list
This will reverse the list:
>>> l1 = [1, 2, 3]
>>> l2 = while_version(l)
>>> l2
[3, 2, 1]
Note, however, that it also empties the original list:
>>> l1
[]
To avoid this, call e.g. l2 = while_version(l1[:]).

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]
>>>

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.

I have no idea what the '::' means Please read about ranges in python. They are used all the time and you really need to understand them. There is reverse() and reversed() in python. One changes the list and the other doesn't change the list, but iterates through it from the back.

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.

Python Program to Reverse List
January 3, 2026 - In this program, we declared a list of numbers and an empty list to store the reversed items. Next, len(a) – 1 returns the last index item in a given list. It means initializing the counter variable to the last index position. Here, the while loop will start iterating the list items from the last index position to the first position (i >= 0).

May 27, 2025 - If you're working with a list, a string, or any other sequence in Python, you can reverse that sequence using Python's slicing syntax: >>> colors = ["purple", "blue", "green", "pink", "red"] >>> colors[::-1] ['red', 'pink', 'green', 'blue', 'purple'] The syntax looks weird, but it does work. If we wanted to write a for loop that iterated over our list from the end to the beginning, we could loop over the reversed slice of that list:
