I'm using scrapy to crawl multiple pages on a site. The variable start_urls is used to define pages to be crawled. I would initially start with 1st page, thus defining start_urls = [1st page] in the file example_spider.py Upon getting more info from 1st page, I would determine what are next pages to be crawled, then would assign start_urls accordingly. Hence, I have to overwrite above example_spid
