title: Calculate text similarity between lists using CountVectorizer, TFIDFVectorizer
body: <p>I would like to see similarity between lists using <code>TFIDFVectorizer</code> and <code>CountVectorizer</code>.</p>
  
  <p>I have lists like below:</p>
  
  <pre class="lang-py prettyprint-override"><code>list1 = [['i','love','machine','learning','its','awesome'],
           ['i', 'love', 'coding', 'in', 'python'],
           ['i', 'love', 'building', 'chatbots']]
  list2 = ['i', 'love', 'chatbots']
  </code></pre>
  
  <p>I would like to see similarity between <code>list1[0]</code> and <code>list2</code>, <code>list1[1]</code> and <code>list2</code> , <code>list1[2]</code> and <code>list2</code>. </p>
  
  <p>Expecting output should be like <code>[0.99 , 0.67, 0.54]</code></p>
