Python: How to open a folder on Windows Explorer(Python 3.6.2, Windows 10)

I found a simple method.

import os
path = "C:/Users"
path = os.path.realpath(path)
os.startfile(path)

Other alternatives

import webbrowser, os
path="C:/Users"
webbrowser.open(os.path.realpath(path))

or with os alone

import os
os.system(f'start {os.path.realpath(path)}')

or subprocess

import subprocess,os
subprocess.Popen(f'explorer {os.path.realpath(path)}')

or

subprocess.run(['explorer', os.path.realpath(path)])

Cross platform:

import webbrowser


path = 'C:/Users'

webbrowser.open('file:///' + path)
