The best way to learn is with examples, and Scrapy is no exception. For this reason, there is an example Scrapy project named quotesbot, that you can use to play and learn more about Scrapy. It contains two spiders for http://quotes.toscrape.com, one using CSS selectors and another one using XPath expressions.
The quotesbot project is available at: https://github.com/scrapy/quotesbot. You can find more information about it in the project’s README.
If you’re familiar with git, you can checkout the code. Otherwise you can download the project as a zip file by clicking here.
