input: Write a python function to sort a list in descending order and print each element.
  assert sort_and_print_descending([10, 3, 5, 8, 7]) == [10, 8, 7, 5, 3]
  assert sort_and_print_descending([1, 4, 2, 9, 6]) == [9, 6, 4, 2, 1]
  assert sort_and_print_descending([3, 5, 1, 4, 2]) == [5, 4, 3, 2, 1]
output: def sort_and_print_descending(lst):
      sorted_lst = sorted(lst, reverse=True)
      for element in sorted_lst:
          print(element)
