  def sort_descending(list_items):
      list_items.sort(reverse=True)
      return list_items
  
  assert sort_descending([3, 7, 5, 8, 10]) == [10, 8, 7, 5, 3]
  assert sort_descending([20, 15, 25, 10, 5]) == [25, 20, 15, 10, 5]
  assert sort_descending([1]) == [1]
  assert sort_descending([]) == []
output: def sort_descending(list_items):
      list_items.sort(reverse=True)
      return list_items
