Package it separately if it:

* Is listed on PyPI (
* Has value separate from the 'parent software' (on its own)
* Users might want it without the parent software
* Is pure python, OR
* Doesn't otherwise explicitly require depend on the parent software

software components are different (main software, python package), I'd
go for separate packaging unless there's a good reason not to.
