title: How do you use pandas isin() function when each row is a list?
body: <p>For example:</p>
  
  <pre><code>import pandas as pd
  data = ['A2', 'A5', 'XS', '2X', '8W']
  codes = {'codes':[data]}
  df = pd.DataFrame(codes)
  
                    codes
  0  [A2, A5, XS, 2X, 8W]
  </code></pre>
  
  <p>Now I want to test to see if certain values are in my list from another list.</p>
  
  <pre><code>df['wo'] = df.codes.isin(["8C", "8D", "8E", "8W", "A2"])
  </code></pre>
  
  <p>I keep getting <code>TypeError: unhashable type: 'list'</code>
  How do I fix this?</p>
