input: Write a function to sort the list items in descending order. The function should take a list as input and return the list sorted in descending order.
  assert sort_list_descending([3, 7, 5, 8, 10])==[10, 8, 7, 5, 3]
  assert sort_list_descending([1, 2, 3, 4, 5])==[5, 4, 3, 2, 1]
  assert sort_list_descending([10, 9, 8, 7, 6])==[10, 9, 8, 7, 6]
  assert sort_list_descending([])==[]
  assert sort_list_descending([5])==[5]
output: def sort_list_descending(lst):
      return sorted(lst, reverse=True)
