[Tutor] funny behaviour

[Jacob Abraham]

Dear Tutors,

   A class was created to extend timedelta to add and
subtract months. Simple doctests that simply create an
instance of the class failed. Could someone please
explain this really funny behaviour.

Regards,
Jacob Abraham

from datetime import datetime, timedelta

class WeirdTimeDelta(timedelta):
    """Allows addition and subtraction of months.

    Variables are getting passed to the timedelta
constructor ??

    >>> delta = WeirdTimeDelta(5)
    >>> delta.days
    0

    Should'nt this work ???

    >>> delta = WeirdTimeDelta(months=5)

    """

    def __init__(self, months=0, *vals, **kwds):
        """Constructs a weird time delta."""
        super(WeirdTimeDelta, self).__init__(*vals,
**kwds)
        self.months = months

if __name__ == "__main__":
    import doctest
    doctest.testmod()
