Proper implementation of os.startfile to launch a target file/URL

shopen

shopen is a proper implementation of os.startfile to launch a target file/URL. Use it to launch the preferred system viewer for the user to view or edit a target file or URL.

---

Usage

Simply install as a dependency of your project and then use it to launch an opener for a file or URL:

import pathlib
import shopen
shopen.open("https://zombo.com/")  # Opens web browser
shopen.open(pathlib.Path("~/somefile.txt").expanduser())  # Opens file viewer

Why?

Python's standard library provides nice cross-platform utilites for lots of different purposes, but so far no simple file/URL opener that would work on all platforms.

On Windows there's os.startfile, but strangely that doesn't support any other platform.

There was a proposal python/cpython#47427 to implement it as shutil.open, but it was rejected for now. Python users keep asking for a decent way to do it, but the only answer had been brittle copypasta… until now!

Ideally this can be added into stdlib after proving its usefulness and then only be needed as a polyfill for older versions of python.
