Can't speak for the science libraries as I've never used em, and I'll gladly just blindly accept that as truth, but for everything else it's always a pain in the ass. For being designed to "run on anything" it sure is funny that 90% of the time I download a python app it doesn't fucking work and requires me to look up and manually setup a specific environment for it. Doesn't help that the error messages are usually completely random and unrelated to this...

I always dread when some fucking madman makes the installer for their app in python, knowing it'll probably fail... God forbid it's a script that's supposed to modify something else. Always a good time for reflection upon the choices that led me to this point.

Even my old scripts I kept around for sentimental value. Half of those don't work either, and I can't be bothered to figure out what version I made em for.

I tried my best to scrub python from my pc out of principle, but as you say, it's soo common my distro uses it as a dependency, fucking bullshit!
