Hello,

That's because datetime does not return NotImplemented in Python 2.7 when compared with unsupported values, so we cannot intercept comparison operators and override their behaviour with infinities.

This issue is related to #5 and cannot be solved for Python 2.7. In Python 3, your snippet works, and leads to [datetime.date(2020, 11, 29),+inf).

Thanks for your response, If possible can you share workaround if you have. Otherwise i will plan to use python3 itself.
This module is very helpful to get the interval information.

Hello,

Unfortunately, there is no easy workaround for this. I strongly recommends switching to Python 3, notably because Python 2.7 is no longer officially supported since January 2020, but also because it is not supported by portion and you're likely to have other issues.
