"First, it's more obvious that you are using a method or instance attribute "
"instead of a local variable.  Reading ``self.x`` or ``self.meth()`` makes it "
"absolutely clear that an instance variable or method is used even if you "
"don't know the class definition by heart.  In C++, you can sort of tell by "
"the lack of a local variable declaration (assuming globals are rare or "
"easily recognizable) -- but in Python, there are no local variable "
"declarations, so you'd have to look up the class definition to be sure.  "
"Some C++ and Java coding standards call for instance attributes to have an "
"``m_`` prefix, so this explicitness is still useful in those languages, too."
msgstr ""
"Tout d'abord, il est plus évident d'utiliser une méthode ou un attribut "
"d'instance par exemple au lieu d'une variable locale. Lire ``self.x``  ou "
"``self.meth()`` est sans ambiguité sur le fait que c'est une variable "
"d'instance ou une méthode qui est utilisée, même si vous ne connaissez pas "
"la définition de classe par cœur. En C++, vous pouvez les reconnaitre par "
"l'absence d'une déclaration de variable locale (en supposant que les "
"variables globales sont rares ou facilement reconnaissables) - mais en "
"Python, il n'y a pas de déclarations de variables locales, de sorte que vous "
"devez chercher la définition de classe pour être sûr. Certaines normes de "
"codages C++ et Java préfixent les attributs d'instance par ``m_``. Cette "
"syntaxe explicite est ainsi utile également pour ces langages."

#: ../src/Doc/faq/design.rst:131
msgid ""
"Second, it means that no special syntax is necessary if you want to "
"explicitly reference or call the method from a particular class.  In C++, if "
"you want to use a method from a base class which is overridden in a derived "
"class, you have to use the ``::`` operator -- in Python you can write "
"``baseclass.methodname(self, <argument list>)``.  This is particularly "
"useful for :meth:`__init__` methods, and in general in cases where a derived "
"class method wants to extend the base class method of the same name and thus "
"has to call the base class method somehow."
msgstr ""
"Ensuite, ça veut dire qu'aucune syntaxe spéciale n'est nécessaire si vous "
"souhaitez explicitement référencer ou appeler la méthode depuis une classe "
"en particulier. En C++, si vous utilisez la méthode d'une classe de base "
"elle-même surchargée par une classe dérivée, vous devez utiliser l'opérateur "
"``::`` -- en Python vous pouvez écrire ``baseclass.methodname(self, "
"<argument list>)``. C'est particulièrement utile pour les méthodes :meth:"
"`__init__`, et de manière générale dans les cas où une classe dérivée veut "
"étendre la méthode du même nom de la classe de base, devant ainsi appeler la "
"méthode de la classe de base d'une certaine manière."

"Finally, for instance variables it solves a syntactic problem with "
"assignment: since local variables in Python are (by definition!) those "
"variables to which a value is assigned in a function body (and that aren't "
"explicitly declared global), there has to be some way to tell the "
"interpreter that an assignment was meant to assign to an instance variable "
"instead of to a local variable, and it should preferably be syntactic (for "
"efficiency reasons).  C++ does this through declarations, but Python doesn't "
"have declarations and it would be a pity having to introduce them just for "
"this purpose.  Using the explicit ``self.var`` solves this nicely.  "
"Similarly, for using instance variables, having to write ``self.var`` means "
"that references to unqualified names inside a method don't have to search "
"the instance's directories.  To put it another way, local variables and "
"instance variables live in two different namespaces, and you need to tell "
"Python which namespace to use."
msgstr ""
"Enfin, pour des variables d'instance, ça résout un problème syntactique pour "
"l'assignation : puisque les variables locales en Python sont (par "
"définition !) ces variables auxquelles les valeurs sont assignées dans le "
"corps d'une fonction (et n'étant pas déclarées explicitement globales), il "
"doit y avoir un moyen de dire à l'interpréteur qu'une assignation est censée "
"assigner une variable d'instance plutôt qu'une variable locale, et doit de "
"préférence être syntactique (pour des raisons d'efficacité). C++ fait ça au "
"travers de déclarations, mais Python n'a pas de déclarations et ça serait "
"dommage d'avoir à les introduire juste pour cette raison. Utiliser "
"explicitement ``self.var`` résout ça avec élégance. Pareillement, pour "
"utiliser des variables d'instance, avoir à écrire ``self.var`` signifie que "
"les références vers des noms non-qualifiés au sein d'une méthode n'ont pas à "
"être cherchés dans l'annuaire d'instances. En d'autres termes, les variables "
"locales et les variables d'instance vivent dans deux différents espaces de "
"noms, et vous devez dire à Python quel espace de noms utiliser."
