Keep reading the python tutorial you're working through and you'll eventually see they import 3rd party libraries. That's when things get difficult.

I keep my 3rd party libraries to a bare minimum as I actually know how to code.

The time it takes to write a utility function is less than the long term pain of dependency hell and all this tooling.

I suggest you go read through your CS 101 textbook.

Surely everyone working on codebases large enough to require package management has the flexibility to make unilateral architectural decisions and re-solve problems a battle-tested library already solved, having mitigated all of the counterintuitive edge cases and security holes you haven't discovered yet. Well, maybe not, but please, please don't let reality discourage you from vigorously patting yourself on the back for not being stymied by limitations that weren't imposed on you.

- Open piano

- Push keys in the correct order

If you forget what order to push the keys, it's literally written on the sheet in code easy enough for young children to decipher. I don't understand the kerfuffle.

Yes, you don’t need a concert hall, a grand piano, or a team of recording engineers to push a key. You are correct.

Right. Everything can be reduced to a simple problem if you ignore enough important details.
