title: pandas value_counts() with multiple values in list form?
body: <p>I'm trying to do a value_count for a specific column in my dataframe</p>
  
  <p>For example:</p>
  
  <pre><code>    &lt;Fruit&gt;
  0   'apple'
  1   'apple, orange'
  2   'orange'
  </code></pre>
  
  <p>How do I sum it so it will count it even if it is in a list? So the above should give me:</p>
  
  <pre><code>'Apple'   2
  'Orange'  2
  </code></pre>
  
  <p>I tried turning the string into a list, but not sure how to value_count over fields with a list of values. </p>
