How can I open Finder.app (on macOS), explorer.exe (on Windows), Gnome or similar (user's choice? on Linux) into a folder with a file highlighted using Python.
In macOS terminal
open -R /path/to/file
reveals the file in Finder.
In Windows
explorer /select,"C:\path\to\file"
seems to do the same thing.
What's the most reliable cross-platform implementation that is available in Python?
