Private attributes / Methods in Python

[Gillou]

AFAIK, Python has not the equivalent of  Java "private" keyword to restrict
access to methods or attributes.
By convention, all methods and attributes which name start with :

* "__" must be considered as "private" (don't use from outside of the class
body)
* "_" must be considered as "restricted" (don't use from outside the class
body or a subclass)

That's the way I'm doing private and restricted methods/attributes in
Python.
Of course, as this is only a notation but not a language feature, a
construct such "anobjectOtherThanSelf.__attribute" works but shows that this
should not be used.
