title: Scrapy read list of URLs from file to scrape?
body: <p>I've just installed scrapy and followed their simple dmoz <a href="http://doc.scrapy.org/en/latest/intro/tutorial.html">tutorial</a> which works. I just looked up basic file handling for python and tried to get the crawler to read a list of URL's from a file but got some errors. This is probably wrong but I gave it a shot. Would someone please show me an example of reading a list of URL's into scrapy? Thanks in advance.</p>
  
  <pre><code>from scrapy.spider import BaseSpider
  
  class DmozSpider(BaseSpider):
      name = "dmoz"
      allowed_domains = ["dmoz.org"]
      f = open("urls.txt")
      start_urls = f
  
      def parse(self, response):
          filename = response.url.split("/")[-2]
          open(filename, 'wb').write(response.body)
  </code></pre>
