title: Is it possible to filter Pandas DataFrame column if column is a list?
body: <pre><code>import pandas as pd
  
  dafr = pd.DataFrame({'a': [1,2,3], 'b': [[1,2,3],[2,3,4],[3,4,5]]})
  </code></pre>
  
  <p>I try to do something like:</p>
  
  <pre><code>dafr[dafr['b'].isin(2)]
  </code></pre>
  
  <p>which should return rows that has lists: [1,2,3] &amp; [2,3,4]. </p>
  
  <p>I wonder if this is possible?</p>
