Just to keep myself sane...

    def date_range(start=None, end=None):
        if start == None:
            start = datetime.date.today()
        if end == None:
            end = datetime.date.today()
        return end - start

Are you saying the "if" statements will raise TypeError if start or end are dates? That would be a sad day for Python. Perhaps you're saying that there is a "meaningful comparison" between None and anything else, but please clarify if so.
