Python's standard library is big. I wouldn't call it great, because Python is over 30 years old and it's hard to add things to a standard library and even harder to remove them.
I’m still hoping we can get a decently typed argparse with a modern API though (so much better for tiny scripts without deps!)
Argument parsing, in partucular, is a great place to start realizing that you can implement what you need without adding a dozen dependencies
Don't disagree with the principle, there are a lot of trivial pythong deps, but rolling your own argument parsing is not the way
If youve never thought about it, it might seem like you need an off-the-shelf dependency. But as programmers sometimes we should think a bit more before we make that decision.
It's a very different story with heavyweight dependencies like Numpy (which include reams of tests, documentation and headers even in the wheels that people are only installing to be a dependency of something else, and covers a truly massive range of functionality including exposing BLAS and LAPACK for people who might just want to multiply some small matrices or efficiently represent an image bitmap), or the more complex ones that end up bringing in multiple things completely unrelated to your project that will never be touched at runtime. (Rich supports a ton of wide-ranging things people might want to do with text in a terminal, and I would guess most clients probably want to do exactly one of those things.)
