title: Python check if element of array contains string
body: <p>I have an array that has 1 element. This element contains:
  print(results_read[0])</p>
  
  <pre><code>[(u'n04019541', u'puck', 0.57829314), (u'n02974003', u'car_wheel', 0.24903433), (u'n03483316', u'hand_blower', 0.025689969), (u'n02910353', u'buckle', 0.015434729), (u'n04542943', u'waffle_iron', 0.012205523)]
  </code></pre>
  
  <p>How can I check if it contains 'car_wheel'? 
  I tried:</p>
  
  <pre><code>if 'car_wheel' in results_read:
        print('yes')
  else:
      print('no')
  </code></pre>
  
  <p>Is there any other way to do this?</p>
