Python Web Scraping Cookbook

By: Michael Heydt

Overview of this book

Python Web Scraping Cookbook is a solution-focused book that will teach you techniques to develop high-performance scrapers and deal with crawlers, sitemaps, forms automation, Ajax-based sites, caches, and more. You'll explore a number of real-world scenarios where every part of the development/product life cycle will be fully covered. You will not only develop the skills needed to design and develop reliable performance data flows, but also deploy your codebase to AWS. If you are involved in software engineering, product development, or data mining (or are interested 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 the websites to writing a sophisticated web crawler, the book's independent recipes will be a godsend. This book covers Python libraries, requests, and BeautifulSoup. You will learn about crawling, web spidering, working with Ajax websites, paginated items, and more. You will also learn 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 able to deploy and operate your scraper in the cloud.

Adding an API to find the skills for a job listing

In this recipe, we add an additional operation to our API which will allow us to request the skills associated with a job listing. This demonstrates a means of being able to retrieve only a subset of the data instead of the entire content of the listing. While we will only do this for the skills, the concept can be easily extended to any other subsets of the data, such as the location of the job, title, or almost any other content that makes sense for the user of your API.

Getting ready

The first thing that we will do is add a scraping function to the sojobs module. This function will be named get_job_listing_skills. The following is the code for this function:
