What is the difference with 2nd example directly
Yes you're right.
But the class and instance thing made me believe the context would be
different.
Error of judgment.

Methods *are* functions. (Technically, they are lightweight wrappers

Shame on me :-[ Steven !
Your example shows me obvious.

If I understand a little bit what happen in:

Try to determine the objects you need for your problem and next step is
how arrange it together (relational).

That's I figured out with MI and super.

Hello Steven,
(1) slots = [] doesn't do anything special. You have misspelled
__slots__.
Yes sorry my mistake :-[
(2) Classes don't become read only just because you add __slots__ to
them. All you prevent is adding extra attributes, and why would you
wish to do that?
I know this is ugly
.
Thanks!

Hello,
I am wondering what is this special class attribut. I know __dict__,
slots. I use slots = [] when I want to use a read only class.
But is anyone could explain with a little example the use of __weakref__?

/home/karim/guiObserver/observable.py, line 11, in attach
self._observers.append(observer)
AttributeError: 'ListObservable' object has no attribute '_observers'
And the Observable class is:
class Observable(object):
Sujet a observer
def __init__(self):
self._observers
).
The code is working but I am not totally happy because of many
EntryObserver almost identical objects (except from update and grid()
options)
Is it possible to simplify this structure?

Karim
The rest of the code is below:
#!/usr/bin/env python2.7
Module ObserverGraphique.py
Une
IN 3.1 for print():
print('hello', end =' ')
hello
It suppress the newline character.
