input: Write a function to sort the given list items in descending order using Python's built-in sort method. Return the sorted list. If the list is empty, return the empty list. The function should use the `reverse=True` parameter to achieve the descending order.
  assert sort_descending([3, 7, 5, 8, 10])==[10, 8, 7, 5, 3]
  assert sort_descending([])==[]
output: def sort_descending(items):
      items.sort(reverse=True)
      return items
