title: Tuple value by key
body: <p>Is it possible to get Value out of tuple:</p>
  
  <pre><code>TUPLE = (
      ('P', 'Shtg1'),
      ('R', u'Shtg2'),
      ('D', 'Shtg3'),
  )
  </code></pre>
  
  <p>by calling STR key like <code>P</code></p>
  
  <p>Python says that only int can be used for this type of 'query'</p>
  
  <p>I can't use loop (too much overhead...)</p>
  
  <p>Thank you!</p>
