Recommend pre-commit in Code Style section

The Code Style section discusses the use of PEP8 and autopep8. Yelp's pre-commit framework allows you to formalise the use of PEP8 in a project by ensuring that PEP8/PyFlakes is run on Python code (as well as equivalent tools for other languages like JSHint). Pre-commit is not mandatory: it is something which individual developers on a project can install if they feel like it - the pre-commit framework simply allows you to share around a common set of pre-commit scripts in a sensible way.

If it is desirable to follow "Pythonicity" in a project, it is probably a good idea to suggest people enforce it at the level of version control.

If there's interest in this, I can draft some text for inclusion and submit a PR.

Commencez par la section Code Style, en particulier par sa présentation de PEP8 et autopep8, et examinez comment le guide présente actuellement les outils de style. La tâche est terminée lorsque la section couvre clairement la recommandation proposée pour pre-commit et son caractère facultatif, tout en conservant la cohérence des indications existantes.
