What is Web Scraping?
Before we move forward with this good agenda, let us take a helpful step and get to know what Web scraping is all about. After that, we shall all be in the same space as we look for resources to learn this beautiful technology.
Web Scraping in simple language is the extraction of data from websites. Since there are many websites out there, tools have been developed that go over the websites (web crawling) looking for specific pieces of data and collecting them automatically (Web Scraping). As you can guess, most of this data is being collected in an unstructured fashion in HTML form. This is later converted into structured data for example in a spreadsheet or some form of a database so that it can be utilised in various ways.
Such information in huge amounts can be pretty invaluable for companies that wish to know trends or organizations looking for particular information about something of their interest. This makes Web Scraping such a sought-after skill that the books we will present next intend to instruct. The books are listed in no particular order and they include the following:
