Python: generic webbrowser.get().open() for chrome.exe does not work

Question

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         


        

Answer 1

You have to use unix-style paths in the webbrowser.get call:

webbrowser.get("C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s").open("http://google.com")

This is because webbrowser internally does a shlex.split on the path, which will just erase Windows-style path separators:

>>> cmd = "C:\\Users\\oreild1\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe %s"
>>> shlex.split(cmd)
['C:Usersoreild1AppDataLocalGoogleChromeApplicationchrome.exe', '%s']
>>> cmd = "C:/Users/dan/AppData/Local/Google/Chrome/Application/chrome.exe %
s"
>>> shlex.split(cmd)
['C:/Users/dan/AppData/Local/Google/Chrome/Application/chrome.exe', '%s']

shlex will actually do the right thing here if given the posix=False keyword argument, but webbrowser won't supply that, even on Windows. This is arguably a bug in webbrowser.
