Выращивание Python с обратной связью Click?

Question

Я пытаюсь использовать привязки Growl Python (Growl.py v0.7 из репозитория Growl), чтобы написать небольшое приложение. Одна из функций, которые в настоящее время отсутствуют, - это уведомление кликов, отправленное на Python.

Я знаю в Objective-C, когда пользователь нажимает уведомление, он отправит триггер запущенному приложению. Я бы хотел сделать аналогичную вещь с привязками Python. Когда пользователь нажимает на уведомление, я хотел бы, чтобы программа Python открывала URL-адрес в браузере (или обрабатывала событие другим способом).

Любые мысли о том, как я могу это осуществить?

Обновление: благодаря synhesizerpatel, который предоставляет многообещающее решение, и я беру его слова, которые он работал на Lion. К сожалению, я начинаю исчезать с Mac, поэтому я больше не занимаюсь программированием Mac. Хотя, я сделал некоторые отладки, как это до сих пор не работает на Snow Leopard, и вот почему:

Discussion Growl PyObjC not working with PyObjC 2.2b3

Является ли это то, что вы хотите?

#!/usr/bin/env python 
# 
# pyGrr! 
# 
# This code was originally found @ 
# http://www.cocoaforge.com/viewtopic.php?f=6&t=13359&p=91992&hilit=pyobjc+growl 
# It is (to the best of our knowledge) the work of user 'tooru' on the same 
# website. 
# 
# I make no claim to this code, all I did was get it working with PyObjC on Lion 
# reformatted it a bit and added some more verbose explanations of what the script 
# does. To be honest, I haven't touched pyobjc in a couple years and I was amazed 
# that it still works! Even more amazed that I was able to get this example working 
# in about 20 minutes. 
# 
# Great job tooru! 
# 
# I have verified this code works with the following combination of 
# packages/versions 
# 
# * OSX Lion 10.7.3 
# * Python 2.7 
# * Growl 1.3 
# * Growl SDK 1.3.1
