Example Spider

Here's a simple example of a Scrapy spider that crawls a website and extracts the titles of the pages:

import scrapy

class MySpider(scrapy.Spider):
    name = 'example_spider'
    start_urls = ['http://example.com']

    def parse(self, response):
        for title in response.css('title::text').extract():
            yield {'title': title}

To run the spider, navigate to the myproject directory and execute the following command:

scrapy crawl example_spider
