Field() This may seem complicated at first, but defining an item class allows you to use other handy components and helpers within Scrapy. Our first Spider Spiders are classes that you define and Scrapy uses links to the Crawler object to which this spider instance is bound. Crawlers encapsulate a lot of components in the project for their single entry access (such as extensions, middlewares, signals managers dictionary-like API with a convenient syntax for declaring their available fields. Various Scrapy components use extra information provided by Items: exporters look at declared fields to figure out columns
