Why can't I subclass datetime.date?

Question

Why doesn\'t the following work (Python 2.5.2)?

>>> import datetime
>>> class D(datetime.date):
        def __init__(self, year):
                  


        

Answer 1

You should probably use a factory function instead of creating a subclass:

def first_day_of_the_year(year):
  return datetime.date(year, 1, 1)
