La versi\u00f3n del proyecto Brython 3.14.1 (Browser Python) est\u00e1 disponible, implementando el lenguaje de programaci\u00f3n Python 3 para navegadores web, lo que permite usar Python en lugar de JavaScript para desarrollar scripts para la Web. El c\u00f3digo del proyecto est\u00e1 escrito en Python y se distribuye bajo la licencia BSD. <\/p>\n

Al conectar las bibliotecas brython.js y brython_stdlib.js, un desarrollador web puede utilizar el lenguaje Python para definir la l\u00f3gica de funcionamiento del sitio en el lado del cliente, utilizando Python en lugar de JavaScript. Para incluir c\u00f3digo Python en las p\u00e1ginas, se utiliza la etiqueta con el tipo MIME 'text\/python'. Se permite tanto la incorporaci\u00f3n del c\u00f3digo en la p\u00e1gina como la carga de scripts externos (). El script proporciona acceso completo a los elementos y eventos del DOM. Adem\u00e1s del acceso a la biblioteca est\u00e1ndar de Python, se ofrecen bibliotecas especializadas para interactuar con el DOM y con bibliotecas de JavaScript como jQuery, D3, Highcharts y Raphael. Se soporta el uso de frameworks CSS como Bootstrap3, LESS y SASS. <\/p>\n

El rendimiento final de la mayor\u00eda de las operaciones en los scripts de Python integrados en las p\u00e1ginas web es similar al rendimiento de CPython. La latencia solo se produce en la etapa de compilaci\u00f3n, pero para solucionarlo se ofrece la posibilidad de cargar c\u00f3digo previamente compilado a JavaScript, que se aplica para acelerar la carga de la biblioteca est\u00e1ndar (Brython proporciona herramientas para crear bibliotecas de JavaScript basadas en m\u00f3dulos de Python). <\/p>\n

La nueva versi\u00f3n se destaca por una reestructuraci\u00f3n completa de la implementaci\u00f3n de los tipos integrados y la reescritura del c\u00f3digo para el an\u00e1lisis de argumentos de funciones y m\u00e9todos incorporados. En la rama Brython 3.14 se asegura la compatibilidad con CPython 3.14 y se implementa la mayor parte de las nuevas caracter\u00edsticas de esta versi\u00f3n, incluyendo el soporte para cadenas de tipo t y la diferida manejo de anotaciones.
