Ahem, oh, uh! You're right, of course. I ever initialize instance
variables as class variables first in Python. I don't know why, but I
use "__init__" very seldom to initialize them to a fixed value (like
None). Only if they are initialized via parameters of "__init__". 

Later on, if the program is running I delete the unnecessary ones,
sometimes :-}

You're right in that one! It was really only for educational purpose.
Normally I also would use "cmp". Especially, as "<", ">" and "==" in
my example also would use "cmp" at last :-)

But I have thought, that it was not very clear, if I show, that
"__cmp__" has to use "cmp" to do its work :-) Perhaps I was wrong
here!

But now, thanks of your friendly correction, he can see, how a profi
would do it the right way :-)))
