title: Check list or strings to see if a string from another list is present
body: <p>I have a list of strings in ListA, and I need to check if any string from listA is in the ith element of listB. If yes, I need to append a string to listB.</p>
  
  <p>For example</p>
  
  <pre><code>ListA =  [['Chicago'], ['Rockford'], ['Aurora']]
  
  ListB = [['Town', 'Population', 'ZipCode'], ['Chicago Heights', '250,000', '12345'], ['Dallas', '1,700,000', '23456']]
  </code></pre>
  
  <p>If any string in ListA, is at some point of the string in ListB[0-2][0], I need to append another string to end of the ListB[0-2].</p>
  
  <p>The output would be </p>
  
  <pre><code>ListC = [['Town', 'Population', 'ZipCode','not illinois'], ['Chicago Heights', '250,000', '12345', Illinois], ['Dallas', '1,700,000', '23456','not Illinois']]
  </code></pre>
  
  <p>Thanks in Advance!</p>
