title: How to do word count on pandas dataframe
body: <p>I know this is may be silly, but every research I've done for this question is led to more complex questions, I still can't figure out the basics, I just want to count the frequency of words</p>
  
  <p>Here's my data</p>
  
  <pre><code>id descriptions
  1  I love you
  2  I love you too
  </code></pre>
  
  <p>Here's my expected output</p>
  
  <pre><code>id descriptions      word count
  1  I love you        3
  2  I love you too    4
  </code></pre>
