title: converting numpy array into dictionary
body: <p>I have an array like the following:</p>
  
  <pre><code>[( 1, b'"C"'), ( 2, b'"C#"'), ( 3, b'"D"'), ( 4, b'"D#"'),
   ( 5, b'"E"'), ( 6, b'"F"'), ( 7, b'"F#"'), ( 8, b'"G"'),
   ( 9, b'"G#"'), (10, b'"A"'), (11, b'"A#"'), (12, b'"B"'))]
  </code></pre>
  
  <p>I want to convert this to a dictionary "d" such that when I say
  <code>d[11]</code> I will get <code>"A#"</code>.</p>
  
  <p>EDIT: learnt that dict is a reserved word, so I changed it to "d".</p>
