range() and xrange() take a third parameter that specifies a step. So you can do the following.
range(10, 0, -1)
Which gives
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
But for iteration, you should really be using xrange instead. So,
xrange(10, 0, -1)
Answer from Chinmay Kanchi on Stack OverflowNote for Python 3 users: There are no separate
rangeandxrangefunctions in Python 3, there is justrange, which follows the design of Python 2'sxrange.

I'm doing self-study program in Python and I'm being challenged to create a function that act exactly like the RANGE function, but it reverse the range. Let's call it reverserange().
reverserange(0,5) will return tuple (4, 3, 2, 1, 0)
I can't for the life of me figure it out. I've been trying for a couple hours. I know it requires a for loop...
Can anyone assist?

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").

March 3, 2026 - The loop starts at 5 and is told to count down with a step of -1. Because the stop value 10 is already higher than the start, the sequence is empty from the beginning. The example below shows the correct approach. # Correctly specifying start > end for reverse iteration for i in range(10, 4, -1): print(i, end=' ') # Prints: 10 9 8 7 6 5

I would like my iterator to go backward, like, starting from 100 and going to one. Is there a smart way to do this instead of setting a counter into the loop and making it go down by one every time the loop restarts ?

The reversed() function might be what you're looking for. Return a reverse iterator. seq must be an object which has a __reversed__() method or supports the sequence protocol (the __len__() method and the __getitem__() method with integer arguments starting at 0). ie for i in reversed(range(1, 101)): print(i) output: 100 99 98 97 96 ... 5 4 3 2 1

Python Reverse `for` Loop: A Comprehensive Guide - CodeRivers
January 29, 2025 - If you need to access both the element and its index during reverse iteration, using range() can be more suitable as it allows you to access the index directly. Choose the method of reverse iteration that makes your code the most readable. For simple reverse iteration over a sequence, the reversed() function is usually the best choice as it is more concise and easier to understand. If your reverse loop is part of a larger algorithm, make sure to document the purpose of the loop clearly, especially if the reverse iteration is not immediately obvious from the code. Python reverse for loops provide a powerful and flexible way to iterate over sequences in reverse order.

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]
>>> xs[::-1]
[40, 20, 10, 0]
