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)

for x in reversed(whatever):
do_something()
This works on basically everything that has a defined order, including xrange objects and lists.

You should show what you've tried so far. It's easier to give productive help if we base the help on code you've written. It doesn't require a for-loop though. You can use one, but it would be far more straightforward with a while. Be careful of artificially limiting what tools you consider. More on reddit.com

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'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?

Yes! You can use slicing ([::-1]), reversed(), a for loop, or recursion to reverse a list without using .reverse(). No, slicing creates a new list. The original list remains unchanged.

September 7, 2022 - For example, provided a number n, range() produces integers from 0 up to n-1. In the example above, we passed 5 to the range() function, so the last number printed was 4 (since 5 - 1 = 4). Sometimes, you may not care about the numbers in the range.

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)

October 14, 2024 - The ‘for’ loop iterates through the length of the ‘num’ string in reverse order, starting from the last index and ending at the first index. In each iteration, the current character at the index is added to the ‘reverse’ variable using the ‘+=’ operator. Finally, the reversed string is printed as output: ‘654321’.

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
