title: Check if one of strings in once column found in the other column
body: <p>Im trying to check if one of strings in column <code>Name B</code> is found in column <code>Name A</code> by creating new column <code>Name Check</code>:</p>
  <p>Current Inputs:</p>
  <pre><code>df = pd.DataFrame({&quot;Name A&quot;:{&quot;0&quot;:&quot;John&quot;,&quot;1&quot;:&quot;Sara&quot;,&quot;2&quot;:&quot;Adam&quot;,&quot;3&quot;:&quot;Ahmed&quot;},
                     &quot;Name B&quot;:{&quot;0&quot;:&quot;John, Geroge&quot;,&quot;1&quot;:&quot;Ahemed, Sara&quot;,&quot;2&quot;:&quot;Adam, Nadia&quot;,&quot;3&quot;:&quot;Sara, John&quot;},
                     &quot;Salary&quot;:{&quot;0&quot;:100,&quot;1&quot;:200,&quot;2&quot;:300,&quot;3&quot;:400}})
  
      Name A  Name B        Salary
  0   John    John, Geroge  100
  1   Sara    Ahemed, Sara  200
  2   Adam    Adam, Nadia   300
  3   Ahmed   Sara, John    400
  </code></pre>
  <p>Excepted Output :</p>
  <pre><code>    Name A  Name B        Salary  Name Check
  0   John    John, Geroge  100     True
  1   Sara    Ahemed, Sara  200     True
  2   Adam    Adam, Nadia   300     True
  3   Ahmed   Sara, John    400     False
  4   Nadi    Sara, Nadia   500     True
  5   George  Georg, Mo     600     True
  </code></pre>
  <p>What i have tried :</p>
  <pre><code>df['Name Check'] = df.apply(lambda x: x['Name B'] in x['Name A'] , axis=1)
  </code></pre>
  <p>But the output is all <strong>False</strong>, not sure how to convert column <code>Name B</code> to a list and loop through to check one by one if found in column <code>Name A</code>.</p>
