Web scraping, also often know as screen scraping, web harvesting or web data extraction, primarily, is a technique used for extracting data from the websites.

It uses the world wide web directory to access the huge database through hypertext transfer protocol and compare and analyze the desired content. Though it can be done manually too, an automated process is hassle-free, can handle larger data, and provides higher accuracy of results.

The Art Of Web Scraping

Web Scraping is done extensively with the help of Python.

Reason being that Python is superfast for this job. Python has a library called “Beautiful soup” which is required for extracting the data out of the HTML and XML files.

It works with one’s favorite parser to provide idiomatic ways of navigating, searching, and modifying the parse tree. It makes the job much easier and saves time.

“Beautiful soup” can do a variety of things but it has its limitations too. It cannot send a request to the web page. So, the “request” option is used first, and then Beautiful soup can be used for performing the other tasks. Another python module that is used for getting the URLs is Urllib2.
