How to use the mimesis.Datetime function in mimesis

def d1(self, seed):
        return Datetime(seed=seed)

                            if callable(getattr(Datetime, method))]
        assert len(datetime_methods) > 0
        for method in datetime_methods:
            assert method in dir(future_dt)

def d2(self, seed):
        return Datetime(seed=seed)
