Prior programming experience with Python would be useful but not essential. Anyone with general knowledge of programming languages should be able to pick up the book and understand the principals involved.What You Will Learn * Extract data from web pages with simple Python programming * Build a concurrent crawler to process web pages in parallel * Follow links to crawl a website * Extract features from the HTML * Cache downloaded HTML for reuse * Compare concurrent models to determine the fastest crawler * Find out how to parse JavaScript-dependent websites * Interact with forms and sessions In Detail The Internet contains the most useful set of data ever assembled, most of which is publicly accessible for free. However, this data is not easily usable. It is embedded within the structure and style of websites and needs to be carefully extracted. Web scraping is becoming increasingly useful as a means to gather and make sense of the wealth of information available online. This book is the ultimate guide to using the latest features of Python 3.x to scrape data from websites. In the early chapters, youll see how to extract data from static web pages. Youll learn to use caching with databases and files to save time and manage the load on servers.After covering the basics, youll get hands-on practice building a more sophisticated crawler using browsers, crawlers, and concurrent scrapers. Youll determine when and how to scrape data from a JavaScript-dependent website using PyQt and Selenium. Youll get a better understanding of how to submit forms on complex websites protected by CAPTCHA. Youll find out how to automate these actions with Python packages such as mechanize. Youll also learn how to create class-based scrapers with Scrapy libraries and implement your learning on real websites. By the end of the book, you will have explored testing websites with scrapers, remote scraping, best practices, working with images, and many other relevant topics. Style and approach This hands-on guide is full of real-life examples and solutions starting simple and then progressively becoming more complex. Each chapter in this book introduces a problem and then provides one or more possible solutions. Author Biography Katharine Jarmul is a data scientist and Pythonista based in Berlin, Germany.
