title: Get value from Tuple
body: <p>I am new to python and I am looking for solution for my problem:-
  I have a Tuple like:-</p>
  
  <pre><code>MY_TUPLE_CHOICE = (
      ('INS', 'Instagram'), 
      ('FAB', 'Facebook'),
      ('YOU', 'Youtube'),
      ('TWT', 'Twitter'),
  )
  </code></pre>
  
  <p>Now First I want to get Tuple Value with Key inside Value for example if a key is <strong>'YOU'</strong> it should return me <strong>('YOU', 'Youtube')</strong>.</p>
  
  <p>Second I want to get individual value within Tuplevalue for a key for example key is <strong>'YOU'</strong> it should return me <strong>'Youtube'</strong>.</p>
