  assert split_and_print_numbers("1,2,3,4,5,6,7,8,9") == None  # Should print: 1 2 3 4 5 6 7 8 9
  assert split_and_print_numbers("10,20,30,40") == None  # Should print: 10 20 30 40
  assert split_and_print_numbers("100,200,300") == None  # Should print: 100 200 300
output: def split_and_print_numbers(s):
      numbers = s.split(',')
      for number in numbers:
          print(int(number))
