Do you mean being able to follow the tutorial at https://packaging.python.org/en/latest/tutorials/packaging-p...? I've never needed to do that before but it seems pretty straightforward. So far I haven't seen anyone specifically request that skill in a job posting and I'd consider that a strange question to ask in a skills test for a general developer position.

If you're claiming that it costs $200k to find a competent developer who can create and publish a Python package, that's risible.
