Web scraping with Python


Question

I'd like to grab daily sunrise/sunset times from a web site. Is it possible to scrape web content with Python? what are the modules used? Is there any tutorial available?

Accepted Answer

Use urllib2 in combination with the brilliant BeautifulSoup library:

import urllib2
from BeautifulSoup import BeautifulSoup
# or if you're using BeautifulSoup4:
# from bs4 import BeautifulSoup

soup = BeautifulSoup(urllib2.urlopen('http://example.com').read())

for row in soup('table', {'class': 'spad'})[0].tbody('tr'):
    tds = row('td')
    print tds[0].string, tds[1].string
    # will print date and sunrise

I'd really recommend Scrapy.

Quote from a deleted answer:

  • Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
  • Scrapy has better and fastest support for parsing (x)html on top of libxml2.
  • Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
  • Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.
