How do I list numbers from greatest to lowest?

Question

I have an assignment to take a number and to sort it in a ascending and descending order and then add it together to get a result. I know how to get the number sorted in a ascending order but not descending. For my code I have:

def addition(num):
    listedDes = list(str(num))
    listedDes.sort()
    print("".join(listedDes))
addition(3524)

You know how to sort - the problem reduces down to [How can I reverse a list in Python?](https://stackoverflow.com/questions/3940128/how-can-i-reverse-a-list-in-python) .. this is more awkward then `.sort(reverse=True)` or `.sort(key=lambda x:-x)` but would be a solution. — Patrick Artner, Jan 07 '19 at 17:58

You can sort by Descending by doing like this.

listedDes.sort(reverse=True)

Here's more in the docs: https://docs.python.org/3/howto/sorting.html#ascending-and-descending
