      >>> from datetime import datetime
      >>> dates = [datetime(2019, 12, 31),
      ...          datetime(2019, 1, 1),
      ...          datetime(2019, 11, 30),
      ...          np.nan]
      >>> is_year_end = IsYearEnd()
      >>> is_year_end(dates).tolist()
      [True, False, False, False]
code: def get_function(self):
      def is_year_end(vals):
