Scrapy

Scrapy is a popular web scraping and crawling framework utilizing high-level functionality to make scraping websites easier. In this chapter, we will get to know Scrapy by using it to scrape the example website, just as we did in Chapter 2, Scraping the Data. Then, we will cover Portia, which is an application based on Scrapy which allows you to scrape a website through a point and click interface.

In this chapter we will cover the following topics:

Getting started with Scrapy
Creating a Spider
Comparing different spider types
Crawling with Scrapy
Visual Scraping with Portia
Automated Scraping with Scrapely
