I am on Python 2.7 (Win 8.1 x64) and I want to open a URL in Chrome. As Chrome is only natively supported in 3.3+, I was trying a generic call:
import webbro
You don't need to switch to Unix-style paths -- simply quote the executable.
import webbrowser webbrowser.get('"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" %s').open('http://google.com')
