Esitatud on projekti Brython 3.10 (Browser Python) v\u00e4ljalase, mis sisaldab Python 3 programmeerimiskeele teostust veebibrauseris, v\u00f5imaldades kasutada Pythonit JavaScripti asemel veebiskripti arendamiseks. Projekti kood on kirjutatud Pythonis ja jaotatakse BSD litsentsi alusel. <\/p>\n

Kuna on \u00fchendatud raamatukogud brython.js ja brython_stdlib.js, saab veebiarendaja kasutada Pythonit, et m\u00e4\u00e4ratleda saidi loogika kliendi poolel, asendades JavaScripti Pythoni keele abil. Pythonikoodi lisamiseks lehtedele kasutatakse sildi <script> mime-t\u00fc\u00fcpi «text\/python». Lubatud on nii koodi lisamine otse lehele kui ka v\u00e4listes skriptidesse laadimine (<script type=»text\/python» src=»test.py»>). Skripti kaudu on t\u00e4ielik juurdep\u00e4\u00e4s DOM-i elementidele ja s\u00fcndmustele. Lisaks juurdep\u00e4\u00e4sule Pythoni standardraamatukogale pakutakse spetsialiseeritud raamatukogusid DOM-i ja JavaScripti raamatukogudega, nagu jQuery, D3, Highcharts ja Raphael, integreerimiseks. Toetatakse ka CSS-i raamistiku Bootstrap3, LESS ja SASS kasutamist. <\/p>\n

Enamik veebilehtede sisseehitatud Python-skripte saavutab tulemuste osas CPythoniga sarnase toimivuse. Viivitus tekib ainult kompileerimise etapis, kuid selle k\u00f5rvaldamiseks on v\u00f5imalus laadida eelnevalt kompileeritud JavaScripti kood, et kiirendada standardraamatukogu laadimist (Brython pakub t\u00f6\u00f6riistu Pythonimoodulite p\u00f5hjal JavaScripti raamatukogude loomiseks). <\/p>\n

Uue v\u00e4ljaande erip\u00e4ra on Python 3.10 \u00fchilduvuse tagamine, sealhulgas mallide teisendamise operaatorite (match\/case) toetamine. Uues versioonis on samuti pakkuda esialgne rakendus keele Python abstraktsest s\u00fcntaksipuust (AST, Abstract Syntax Tree), mida saab hiljem kasutada JavaScripti koodi genereerimiseks universaalsest AST-st.
