I view dependencies outside of the standard library as a kind of technical debt, not because I suffer from Not Invented Here and want to code it myself, no, I look and think, "Why isn't this in the standard library with a working set of idioms around it?"
I haven't developed anything with more than five digits of code to it, which is fine for me, but part of it is just ... avoidance of having to screw with libraries. Ran into a pip issue I won't go into (it requires a lot of justification to see how I got there) and just ... slumped over.
This has been a bad spot in Python for a long, long time. While people are busy cramming their favorite feature from their last language into Python, this sort of thing has languished.
Sadly, I have nothing to offer but encouragement, I don't know the complexities of packaging, it seems like a huge topic that perhaps nobody really dreamed Python would have to seriously deal with twenty years ago.
