La bibliothèque standard
************************

Alors que La référence du langage Python décrit exactement la syntaxe
et la sémantique du langage Python, ce manuel de référence de la
Bibliothèque décrit la bibliothèque standard distribuée avec Python.
Il décrit aussi certains composants optionnels typiquement inclus dans
les distributions de Python.

La bibliothèque standard de Python est très grande, elle offre un
large éventail d'outils comme le montre la longueur de la table des
matières ci-dessous. La bibliothèque contient des modules natifs
(écrits en C) exposant les fonctionnalités du système telles que les
interactions avec les fichiers qui autrement ne seraient pas
accessibles aux développeurs Python, ainsi que des modules écrits en
Python exposant des solutions standardisées à de nombreux problèmes du
quotidien du développeur. Certains de ces modules sont définis
explicitement pour encourager et améliorer la portabilité des
programmes Python en abstrayant des spécificités sous-jacentes en API
neutres.

Les installateurs de Python pour Windows incluent généralement la
bibliothèque standard en entier, et y ajoutent souvent d'autres
composants. Pour les systèmes d'exploitation Unix, Python est
typiquement fourni sous forme d'une collection de paquets, il peut
donc être nécessaire d'utiliser le gestionnaire de paquets fourni par
le système d'exploitation pour obtenir certains composants optionnels.

Au delà de la bibliothèque standard, il existe une collection
grandissante de plusieurs centaine de milliers de composants (des
programmes, des modules, ou des *frameworks*), disponibles dans le
Python Package Index.
