La version du projet Brython 3.11 (Browser Python) a \u00e9t\u00e9 publi\u00e9e, mettant en \u0153uvre le langage de programmation Python 3 pour ex\u00e9cution c\u00f4t\u00e9 navigateur web, permettant d'utiliser Python au lieu de JavaScript pour le d\u00e9veloppement de scripts pour le Web. Le code du projet est \u00e9crit en Python et est distribu\u00e9 sous la licence BSD. <\/p>\n

En connectant les biblioth\u00e8ques brython.js et brython_stdlib.js, le d\u00e9veloppeur web peut utiliser le langage Python pour d\u00e9finir la logique de fonctionnement du site c\u00f4t\u00e9 client, en utilisant Python \u00e0 la place de JavaScript. Pour inclure le code Python sur les pages, on utilise la balise avec le type MIME «text\/python». Il est possible d'incorporer le code directement dans la page ou de charger des scripts externes (<script type=»text\/python» src=»test.py»>). Le script permet un acc\u00e8s complet aux \u00e9l\u00e9ments et \u00e9v\u00e9nements du DOM. En plus de l'acc\u00e8s \u00e0 la biblioth\u00e8que standard de Python, des biblioth\u00e8ques sp\u00e9cialis\u00e9es sont propos\u00e9es pour interagir avec le DOM et les biblioth\u00e8ques JavaScript, telles que jQuery, D3, Highcharts et Raphael. L'utilisation de frameworks CSS comme Bootstrap3, LESS et SASS est \u00e9galement prise en charge. <\/p>\n

La performance finale de la plupart des op\u00e9rations dans les scripts Python int\u00e9gr\u00e9s aux pages web est proche de celle de CPython. Un retard ne se produit qu'\u00e0 l'\u00e9tape de compilation, mais pour y rem\u00e9dier, il est possible de charger du code pr\u00e9compil\u00e9 en JavaScript, ce qui est utilis\u00e9 pour acc\u00e9l\u00e9rer le chargement de la biblioth\u00e8que standard (Brython fournit des outils pour cr\u00e9er des biblioth\u00e8ques JavaScript \u00e0 partir de modules Python). <\/p>\n

La nouvelle version se distingue par sa compatibilit\u00e9 avec CPython 3.11 et la mise en \u0153uvre de la plupart des nouvelles fonctionnalit\u00e9s de cette branche, y compris le support des groupes d'exceptions et de l'expression \u00ab except* \u00bb, la pr\u00e9cision des expressions probl\u00e9matiques dans les messages de diagnostic et l'attachement de notes aux exceptions.
