Form\u00e9<\/a> version du projet PyPy 7.3<\/a><\/noindex>, dans le cadre duquel se d\u00e9veloppe une impl\u00e9mentation du langage Python, \u00e9crite en Python (utilisant un sous-ensemble statiquement typ\u00e9 RPython<\/a><\/noindex>, Python restreint). La version a \u00e9t\u00e9 pr\u00e9par\u00e9e simultan\u00e9ment pour les branches PyPy2.7 et PyPy3.6, garantissant la prise en charge de la syntaxe Python 2.7 et Python 3.6. La version est disponible pour Linux (x86, x86_64, PPC64, s390x, Aarch64, ARMv6 ou ARMv7 avec VFPv3), macOS (x86_64), OpenBSD, FreeBSD et Windows (x86). <\/p>\n

Une caract\u00e9ristique de PyPy est l'utilisation d'un compilateur JIT qui traduit \u00e0 la vol\u00e9e certains \u00e9l\u00e9ments en code machine, ce qui permet d'assurer un<\/a><\/noindex> Niveau de performance \u2014 lors de l'ex\u00e9cution de certaines op\u00e9rations, PyPy surpasse plusieurs fois l'impl\u00e9mentation classique de Python en langage C (CPython). Le prix de cette haute performance et de l'utilisation de la compilation JIT est une consommation de m\u00e9moire plus \u00e9lev\u00e9e \u2014 la consommation totale de m\u00e9moire dans des processus complexes et ex\u00e9cut\u00e9s longtemps (par exemple, lors de la traduction de PyPy par PyPy lui-m\u00eame) d\u00e9passe de 1,5 \u00e0 2 fois celle de CPython. <\/p>\n

Parmi les changements dans la nouvelle version on note<\/a><\/noindex> , mise \u00e0 jour des modules CFFI 1.13.1 (C Foreign Function Interface) et cppyy 1.10.6 avec mise en \u0153uvre de l'interface pour appeler des fonctions \u00e9crites en C et C++ (CFFI est recommand\u00e9 pour interagir avec le code C, et cppyy pour le code C++). La nouvelle version inclut une nouvelle version du package pyrepl avec un shell interactif REPL<\/a><\/noindex>.
\n. Une optimisation des performances du code responsable du traitement des cha\u00eenes et des manipulations Unicode a \u00e9t\u00e9 effectu\u00e9e.
\nPour la plateforme Windows, le support de l'encodage et du d\u00e9codage de diff\u00e9rents encodages texte a \u00e9t\u00e9 ajout\u00e9. Un support pour OpenSSL 1.1 et TLS 1.3 a \u00e9t\u00e9 mis en \u0153uvre.<\/p>\n
