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").

python - How do I reverse a list or loop over it backwards? - Stack Overflow
From a speed perspective, it is best to use the above built-in functions to reverse a list. For reversing, they are 2 to 8 times faster on short lists (10 items), and up to ~300+ times faster on long lists compared to a manually-created loop or generator. This makes sense - they are written ... More on stackoverflow.com

list.reverse() reverses the list in place and returns None. So for i in l.reverse(): is the same as for i in None:. You already figured out one solution. The other one is reversed(l), which will return the reversed list. More on reddit.com

August 30, 2023 - Python has a built-in function called reversed() that returns a reverse iterator. An iterator is an object that contains a countable number of values and can be iterated (looped) upon. Here's a quick example: my_list = [1, 2, 3, 4, 5] for i in reversed(my_list): print(i)

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

>>> xs = [0, 10, 20, 40]

Hello - why is this code not working an i get an error:
l = [1,2,3] for i in l.reverse(): print(i)
and i get this error
Traceback (most recent call last):
File "C:\Users\Polzi\Documents\DEV\Python-Private\temp1.py", line 7, in <module>
for i in l.reverse():
TypeError: 'NoneType' object is not iterable
(NormalScraping) Only this code is working:
l = [1,2,3] l.reverse() for i in l: print(i)
Why is the first code not working?

list.reverse() reverses the list in place and returns None. So for i in l.reverse(): is the same as for i in None:. You already figured out one solution. The other one is reversed(l), which will return the reversed list.

l.reverse reverses the list in-place, so you get None as a return value >>> l = [1,2,3] >>> print(l.reverse()) None and you can't run for i in None: obviously. If you mean to just run the for loop in reverse use reversed instead for i in reversed(l): As a sidenote, next time please use code blocks not code lines, as those will not be formatted when they're too long (as you can see with the exception message)

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]
