title: Link Fetching List
body: <p>so I've asked many questions regarding this one subject, and I'm sorry. But this is it. </p>
  
  <p>So I have this code:</p>
  
  <pre><code>import urllib
  import urllib.request
  from bs4 import BeautifulSoup
  import sys
  from collections import defaultdict
  
  m_num=int(input('Enter number of monsters to look up: '))
  for x in range(m_num):
      name=input("Enter a monster's name: ")
      url_name=name.replace(' ','_')
      url=('http://yugioh.wikia.com/wiki/Card_Tips:{}'.format(url_name))
      page = urllib.request.urlopen(url)
      soup = BeautifulSoup(page.read())
      content = soup.find('div',id='mw-content-text')
      links = content.findAll('a')
      link_lists = defaultdict(list)
      for link in links:
          link_lists[x].append(link.get('title'))
  all_lists = list(link_lists.values())
  common_links = set(all_lists[0]).intersection(*all_lists[1:])
  print('common links: ',common_links)
  </code></pre>
  
  <p>What I'm trying to do is for how many number of monsters the user specifies is how many lists are creatd. Each list is then filled with all the links from that specific site. And then in the ned all the lists are compared to see if they have similar strings inside of them. (Hopefully that makes sense). </p>
  
  <p>So the problem I'm having is that when I run it and it gets to the <code>print('common links:',common_links)</code> part it only prints out the last list. It doesn't compare the lists nor does it even recognize that the other lists were created. </p>
  
  <p>Can anyone lend a helping hand? I've been troubleshooting this and I'm just stuck.</p>
