title: Remove duplicates in a list while keeping its order (Python)
body: <p>This is actually an extension of this question. The answers of that question did not keep the "order" of the list after removing duplicates. <a href="https://stackoverflow.com/questions/1534736/how-to-remove-these-duplicates-in-a-list-python">How to remove these duplicates in a list (python)</a></p>
  
  <pre><code>biglist = 
  
  [ 
  
      {'title':'U2 Band','link':'u2.com'}, 
      {'title':'Live Concert by U2','link':'u2.com'},
      {'title':'ABC Station','link':'abc.com'}
  
  ]
  </code></pre>
  
  <p>In this case, the 2nd element should be removed because a previous "u2.com" element already exists.  However, the order should be kept.</p>
