0908. Sorted? yes? no? how?

Complete the method which accepts an array of integers, and returns one of the following:

"yes, ascending" - if the numbers in the array are sorted in an ascending order

"yes, descending" - if the numbers in the array are sorted in a descending order

"no" - otherwise

You can assume the array will always be valid, and there will always be one correct answer.

Solution:

def is_sorted_and_how(arr):
    if sorted(arr) == arr:
        return "yes, ascending"
    elif sorted(arr, reverse=True) == arr:
        return "yes, descending"
    return "no"
