Q:

Do anyone know how to use python webbrowser.open under window

I had try with python with webbrowser.open, but it only work on IE. How to let it open chrome or firefox. I don't want it to open on IE, i wants to be open on Chrome or Firefox. Due to i try many method, but none of them works. 
import time
import webbrowser
webbrowser.open('www.google.com')

A:

you need specify your webbrowser's name, detal see webbrowser.get
import webbrowser
webbrowser.open('www.google.com')
a = webbrowser.get('firefox')
a.open('www.google.com') # True

UPDATE
If you have chrome or firefox installed in your computer, do as following: 
chrome_path =r'C:\Users\Administrator\AppData\Local\Google\Chrome\Application\chrome.exe' # change to your chrome.exe path  
# webbrowser is just call subprocess.Popen, so make sure this work in your cmd firstly
# C:\Users\Administrator>C:\Users\Administrator\AppData\Local\Google\Chrome\Application\chrome.exe www.google.com

# there two way solve your problem
# you have change \ to / in windows
# this seems a bug in browser = shlex.split(browser) in windows
# ['C:UsersAdministratorAppDataLocalGoogleChromeApplicationchrome.exe', '%s']
a = webbrowser.get(r'C:/Users/Administrator/AppData/Local/Google/Chrome/Application/chrome.exe %s')
a.open('www.google.com')  #True
# or by register 
webbrowser.register('chrome', None,webbrowser.BackgroundBrowser(r'C:\Users\Administrator\AppData\Local\Google\Chrome\Application\chrome.exe'))
a = webbrowser.get('chrome')
a.open('www.google.com')  #True

else you can try selenium, it provide much more functions and only need chromedriver.
