This code is pretty straightforward to translate into python.  It's
pretty short so, I've pasted it inline:

import sys

class Dog(object):
    def __init__(self, name, sound="barks"):
        self.name = name
        self.sound = sound
    def bark(self):
        print "%s %s" % (self.name, self.sound)
    def do_your_thing(self):
        raise NotImplementedError

class Rottweiler(Dog):
    def do_your_thing(self):
        print "%s snarls at you in a menacing fashion." % self.name

class Spaniel(Dog):
    def do_your_thing(self):
        print "%s licks you all over, then drools on you." % self.name

if __name__ == "__main__":
    butch = Rottweiler("Butch")
    mac = Spaniel("Mac", "yips")

    butch.bark()
    mac.bark()

    butch.do_your_thing()
    mac.do_your_thing()
    sys.stdin.readline()

It's probably more pythonic to not define the Dog.do_your_thing()
method at all than to raise the NotImplementedError, but I think that
this way mirrors the VB code a bit better.  I don't think there's a
good way to mark the entire Dog class as abstract in python, which I
think is what the VB code does with the "MustInherit Class Dog" line.
