Semalt: rastreadores Python y herramientas web raspador

En el mundo moderno, el mundo de la ciencia y la tecnología, todos los datos que necesitamos deben estar claramente presentados, bien documentados y disponibles para su descarga instantánea. Entonces, podríamos usar esta información para cualquier propósito y en cualquier momento que lo necesitemos. Sin embargo, en la mayoría de los casos, la información necesaria está atrapada dentro de un blog o sitio. Mientras que algunos sitios hacen esfuerzos para presentar datos en el formato estructurado, organizado y limpio, el otro no puede hacer eso.

El rastreo, el procesamiento, el raspado y la limpieza de datos son necesarios para un negocio en línea. Debe recopilar información de múltiples fuentes y guardarla en las bases de datos propietarias para cumplir sus objetivos comerciales. Tarde o temprano, tendrá que recurrir a la comunidad de Python para obtener acceso a varios programas, marcos y software para capturar sus datos. Aquí hay algunos programas de Python famosos y destacados para rastrear y rastrear los sitios y analizar los datos que necesita para su negocio.

Pyspider

Pyspider es uno de los mejores rastreadores web y rastreadores de Python en Internet. Es conocido por su interfaz fácil de usar y basada en la web que nos facilita el seguimiento de los múltiples rastreos..Además, este programa viene con múltiples bases de datos back-end.

Con Pyspider puede volver a intentar fácilmente páginas web fallidas, rastrear sitios web o blogs por edad y realizar una variedad de otras tareas. Solo necesita dos o tres clics para realizar su trabajo y rastrear sus datos fácilmente. Puede usar esta herramienta en los formatos distribuidos con múltiples rastreadores trabajando a la vez. Está licenciado por la licencia Apache 2 y está desarrollado por GitHub.

MechanicalSoup

MechanicalSoup es una famosa biblioteca de rastreo que se basa en la famosa y versátil biblioteca de análisis HTML, llamada Beautiful Soup. Si considera que su rastreo web debe ser bastante simple y único, debe probar este programa lo antes posible. Hará que el proceso de rastreo sea más fácil. Sin embargo, puede requerir que haga clic en algunas casillas o ingrese texto.

Scrapy

Scrapy es un poderoso marco de web scraping que es apoyado por la comunidad activa de desarrolladores web y ayuda a los usuarios a construir un negocio en línea exitoso. Además, puede exportar todo tipo de datos, recopilarlos y guardarlos en múltiples formatos como CSV y JSON. También tiene algunas extensiones incorporadas o predeterminadas para realizar tareas como el manejo de cookies, spoofs del agente de usuario y rastreadores restringidos.

Otras herramientas

Si no se siente cómodo con los programas descritos anteriormente, puede probar Cola, Demiurge, Feedparser, Lassie, RoboBrowser y otras herramientas similares. No estaría mal decir que la lista está más allá de su finalización y que hay muchas opciones para quienes no les gustan los códigos PHP y HTML.
