Though, it can be done manually too, but an automated process is hassle free, can handle larger data and provided higher accuracy of results.
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 more easier and saves the time. “Beautiful soup” can do a variety of things but it has its own limitation. It cannot send a request on to the web page. So for making the requests, requests are used and then further Beautiful soup can be used. Another python module which is used for getting the URLs is Urllib2 is also used.
