title: indexing and finding values in list of namedtuples
body: <p>I have a namedtuple like the following,</p>
  
  <pre><code>tup = myTuple  (
                  a=...,
                  b=...,
                  c=...,
                  )
  </code></pre>
  
  <p>where ... could be any value(string, number, date, time, etc). Now, i make a list of these namedtuples and want to find, lets say c=1 and the corresponding value of a and b. Is there any pythonic way of doing this?</p>
