Hi!
Everything ... are an object.
It's true ; but a language built around the objects, and OOP, are two
different concepts.

Bonjour !
AMHA, ceux qui ont écrit ce texte ont une mauvaise idée de ce que sont
les variables en Python.
Ils ont sans doute trop en tête les notions des variables en C ou en
Basic, et ne se sont pas penchés sur les spécificités de Python.

You're making a copy of the ds tuple, which has the -same- contents as

satoru,
I should point out that the normal
approach is to just try whatever it
is that you're doing, and let it fail
where it fails. For example:
def processSeq(x):
for i in x:
print i
processSeq([1, 2, 3])
processSeq("foobar")
processSeq(5) <-- This will fail.

I call it an obvious misuse and misunderstanding of why you'd use a class in
the first place. Either create an instance and not make these things
classmethods or just share the stuff in a module-level set of variables. But
the instantiating is the best options. Your class attributes might not be
