title: How can I find the frequency of words in a list of Strings using Counter?
body: <p>Example</p>
  
  <pre><code>text = [
       'this is the first document',
       'this document is the second document',
       'and this is the third one',
       'is this the first document?',
        ]
  </code></pre>
  
  <p>Expected Output</p>
  
  <pre><code> { 'this' : 4 , 
     'is' : 4, 
     'the':4, .....etc}
  </code></pre>
  
  <p>I've tried to use this code but I'm getting word frequency for each sentence rather than for the entire list.</p>
  
  <pre><code>a = dict(Counter(text.split()))
  </code></pre>
