Set default browser on OSX with Python

defaultbrowser.py

#/usr/bin/env python
from LaunchServices import LSSetDefaultHandlerForURLScheme
from LaunchServices import LSSetDefaultRoleHandlerForContentType

# 0x00000002 = kLSRolesViewer
# see https://developer.apple.com/library/mac/#documentation/Carbon/Reference/LaunchServicesReference/Reference/reference.html#//apple_ref/c/tdef/LSRolesMask
LSSetDefaultRoleHandlerForContentType("public.html", 0x00000002, "com.operasoftware.operanext")
LSSetDefaultRoleHandlerForContentType("public.xhtml", 0x00000002, "com.operasoftware.operanext")
LSSetDefaultHandlerForURLScheme("http", "com.operasoftware.operanext")
LSSetDefaultHandlerForURLScheme("https", "com.operasoftware.operanext")

is there any way to make your python program work as a default browser and whenever there is a specific URL lunches chrome or firefox

@wolfpat01 You have probably found out this already, but for other people who might be interested in the same thing: this can be achieved by using Hammerspoon with URLDispatcher extension. Not related to a Python script, but might be useful for some people to know. In addition to that, URLs there can be configured in a flexible manner with the help of regular expressions. Please pay attention that once configures you will need to set Hammerspoon as your default browser for using the aforementioned extension properly.

if you are getting "module not found" run this in your terminal:
pip install pyobjc-framework-LaunchServices
