Item Loaders Populate walk you through an example of a Scrapy Spider using the simplest way to run a spider. Here’s the code for a spider that scrapes famous quotes from website http://quotes.toscrape.com, following the pagination: scraping, you will have to set up a new Scrapy project. Enter a directory where you’d like to store your code and run: scrapy startproject tutorial This will create a tutorial directory with the following contents:
