Esperto di Semalt: Data Scraping - 4 incredibili applicazioni Python

Lo scraping dei dati, noto anche come estrazione dati e scraping web, è la tecnica di estrazione dati da siti Web. Ogni sito ospita informazioni sotto forma di HTML o di alcuni testi statici. Se si desidera analizzare correttamente questi testi, è necessario utilizzare uno strumento di analisi dei dati. Scrapy, ad esempio, è un software per l'estrazione di dati basato su Python che raccoglie informazioni da vari siti e converte i dati non strutturati nella forma strutturata. D'altra parte, BeautifulSoup è la libreria Python progettata per diversi progetti di scraping web e data mining. Sia Scrapy che BeautifulSoup convertono automaticamente i dati non organizzati in un modulo organizzato e forniscono istantaneamente informazioni scalabili e leggibili.

Una panoramica di Python:

Python è un linguaggio di programmazione generico. L'idea di Python ebbe origine nel 1989, quando Guido van Rossum si trovò di fronte alle carenze del linguaggio ABC. Ha iniziato a sviluppare un nuovo linguaggio di programmazione in grado di analizzare i dati da siti dinamici e complicati. Oggi, Python ha diverse implementazioni come Jython, IronPython e la versione PyPy.

I programmatori e gli sviluppatori web preferiscono Python grazie alle sue versatili funzioni e ai codici di programmazione facili da apprendere. Alcune delle più sorprendenti applicazioni di Python sono state discusse di seguito.

 1. Presenza dei moduli di terze parti: 

L'indice dei pacchetti di BeautifulSoup e Python (PyPI) contiene vari moduli di terze parti che vengono utilizzati per raschiare i dati da una grande numero di siti. Uno dei principali vantaggi di Python è la possibilità di sviluppare un numero elevato di strumenti in modo facile e conveniente.

 2. Una vasta gamma di librerie: 

Puoi ottenere benefici dalle diverse librerie Python e grattare quante più pagine web vuoi. Ad esempio, Scrapy semplifica la scansione dei dati in tempo reale.Prima di tutto questo strumento navigherà attraverso diversi siti e raccoglierà informazioni utili per te.Nella fase successiva, questo strumento basato su Python analizzerà i dati come requisiti. Varie attività di estrazione dei dati di alto profilo possono essere eseguite con Python e le sue librerie.

 3. Una lingua open-source: 

Python è stato sviluppato sotto la licenza open source approvata OSI, che è adatto a programmatori, programmatori, sviluppatori e imprese Lo sviluppo di Python è guidato dalla comunità che collabora per i suoi codici attraverso le mailing list e le conferenze di hosting.

 4. Python come linguaggio produttivo: 

Python ha una vasta gamma di framework, l ibridi e software tra cui scegliere. Aiuta ad aumentare la produttività di un programmatore mentre interagisce con JavaScript, Perl, VB, C, C ++ e C #. Puoi usare Python per raschiare dati da file HTML, documenti PDF, immagini, file audio e video.

 Conclusione: 

Rispetto a JDBC e ODBC, il database di Python risulta essere poco sviluppato e primitivo. Questo è il motivo per cui questa lingua è adatta solo a principianti e webmaster. Se vuoi usare Python per gestire siti complessi, potrebbe non essere la lingua giusta per te. Invece, puoi optare per PHP o C ++ e raschiare facilmente i dati da siti complessi. È vero che Python ha un design orientato agli oggetti, ma PHP e C ++ sono di gran lunga migliori di questo linguaggio perché non è necessario imparare troppi codici.
