title: Can I overwrite the string form of a namedtuple?
body: <p>For example:</p>
  
  <pre><code>&gt;&gt;&gt; Spoken = namedtuple("Spoken", ["loudness", "pitch"])
  &gt;&gt;&gt; s = Spoken(loudness=90, pitch='high')
  &gt;&gt;&gt; str(s)
  "Spoken(loudness=90, pitch='high')"
  </code></pre>
  
  <p>What I want is:</p>
  
  <pre><code>&gt;&gt;&gt; str(s)
  90
  </code></pre>
  
  <p>That is I want the string representation to display the loudness attribute.
  Is this possible ?</p>
