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.

r/learnpython on Reddit: Reversing a range using a FOR LOOP
December 24, 2022 -
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?

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.

reverse = () for x in range(a,b): b = b-1 reverse = (x,) + reverse Here is a good way to solve this, I believe I'm also doing the same course.

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:
