How to check if something new appears on a certain web page in Python? : <p>I am scraping a web page using BS4 &amp; Scrapy. Is there a way to check if something new appears? If so, can it be copied and printed out?<br>
For example, <a href="http://www.flashscore.com/match/0foYiLmk/#match-summary" rel="nofollow noreferrer">here</a> is a soccer match that is live as I'm writing this post. Each scored goal is indicated by the player's name, it's time, and the soccer ball, which is <code>span</code> with the class <code>icon soccer-ball</code>. How can I check the page, let's say, every 2 minutes, and print out if someone scores a goal?</p>
