cross platform - Python: Opening a folder in Explorer/Nautilus/Finder

Question

I'm in Python, and I have the path of a certain folder. I want to open it using the default folder explorer for that system. For example, if it's a Windows computer, I want to use Explorer, if it's Linux, I want to use Nautilus or whatever is the default there, if it's Mac, I want to use Finder.

How can I do that?

Answer 1

I am surprised no one has mentioned using xdg-open for *nix which will work for both files and folders:

import os
import platform
import subprocess

def open_file(path):
    if platform.system() == "Windows":
        os.startfile(path)
    elif platform.system() == "Darwin":
        subprocess.Popen(["open", path])
    else:
        subprocess.Popen(["xdg-open", path])
