Next, you'll see learn Spiders specify what to crawl, how to crawl, and how to process scraped data. You'll also learn how you can take your Spiders to the cloud using the Scrapy Cloud. The cloud platform offers advanced scraping functionality including a cutting-edge tool called Portia with which you can build a Spider without writing a single line of code.
