I don't know of a notifier class in the standard library,
but it's not all that difficult to write one. This is the
one I am currently using:

-----------------------------------------------------
# module Notify

class Notify(object):
    def __init__(self):
        self.listenerList = []

    def sendMessage(self, event):
        for callback in self.listenerList:
            callback(event)
        return

    def addListener(self, callback):
        self.listenerList.append(callback)

    def removeListener(self, callback):
        self.listenerList.remove(callback)
-----------------------------------------------------

callback has to be a callable of some kind,
a bound method is perfectly acceptable and
that's what I use. Works great.
