Book Description

Python Web Scraping Cookbook is a solution-focused book that will teach you techniques to develop high-performance Scrapers, and deal with cookies, hidden form fields, Ajax-based sites and proxies. You'll explore a number of real-world scenarios where every part of the development or product life cycle will be fully covered. You will not only develop the skills to design reliable, high-performing data flows, but also deploy your codebase to Amazon Web Services (AWS). If you are involved in software engineering, product development, or data mining or in building data-driven products, you will find this book useful as each recipe has a clear purpose and objective.

Right from extracting data from websites to writing a sophisticated web crawler, the book's independent recipes will be extremely helpful while on the job. This book covers Python libraries, requests, and BeautifulSoup. You will learn about crawling, web spidering, working with AJAX websites, and paginated items. You will also understand to tackle problems such as 403 errors, working with proxy, scraping images, and LXML.

By the end of this book, you will be able to scrape websites more efficiently and deploy and operate your scraper in the cloud.

What you will learn

• Use a variety of tools to scrape any website and data, including Scrapy and Selenium
• Master expression languages, such as XPath and CSS, and regular expressions to extract web data
• Deal with scraping traps such as hidden form fields, throttling, pagination, and different status codes
• Build robust scraping pipelines with SQS and RabbitMQ
• Scrape assets like image media and learn what to do when Scraper fails to run
• Explore ETL techniques of building a customized crawler, parser, and convert structured and unstructured data from websites
• Deploy and run your scraper as a service in AWS Elastic Container Service
