Why does scrapy crawl quotes result in a GET error? - scrapy

Question

I have generated the quotes spider in the tutorial, and I have added a yield option to parse. However, the spider is not working because it is having an issue downloading quotes.toscrape.com.
# -*- coding: utf-8 -*-
import scrapy
class QuotesSpider(scrapy.Spider):
name = "quotes"
allowed_domains = ["quotes.toscrape.com"]
start_urls = (
'http://www.quotes.toscrape.com/',
)
def parse(self, response):
h1_tag = response.xpath('//h1/a/text()').extract_first()
tags = response.xpath('//*[#class="tag-item"]/a/text()').extract()
yield {'H1 Tag': h1_tag, 'Tags': tags}

Answer 1

This should actually yield the correct result. The error was a syntax error.
