Python class __init__(mandatory arguments?)

One may as well begin with Bengt Richter's letter to comp.lang.python:

Yep.  I just realised this when re-reading the posts.  Of
course, it should've been the other way round.  My
on-the-fly-example was bad and I would've realised if I had at
least tested it first.  :-(

You're right.  I'm learning by building a command-line router
controller (to bring the WWW link up and down) and using Dive
Into Python (.org) and the python.org tutorial as reference
material.  In my code, I assigned initial values to the
__init__() arguments (eg. def __init__(self, param1=None,
param2=None) - which is what made the arguments optional.  Doh!

Thanks again (I'm sorted now) ;-)
