If programming is magic then web scraping is surely a
form of wizardry. By writing a simple automated program, you can query
web servers, request data, and parse it to extract the information you
need. The expanded edition of this practical book not only introduces
you web scraping, but also serves as a comprehensive guide to scraping
almost every type of data from the modern web.
Part I focuses on
web scraping mechanics: using Python to request information from a web
server, performing basic handling of the server's response, and
interacting with sites in an automated fashion. Part II explores a
variety of more specific tools and applications to fit any web scraping
