  Examples: |

      >>> f.month_lengths = numpy.array([34, 31, 32, 30, 29, 27, 28, 28, 28, 32, 32, 34])
      >>> f.month_lengths
      (34, 31, 32, 30, 29, 27, 28, 28, 28, 32, 32, 34)
      >>> del f.month_lengths

      >>> f.setprop('month_lengths', [34, 31, 32, 30, 29, 27, 28, 28, 28, 32, 32, 34])
      >>> f.getprop('month_lengths')
      (34, 31, 32, 30, 29, 27, 28, 28, 28, 32, 32, 34)
      >>> f.delprop('month_lengths')
