title: Ignore part of a python tuple
body: <p>If I have a tuple such as <code>(1,2,3,4)</code> and I want to assign 1 and 3 to variables a and b I could obviously say</p>
  <pre><code>myTuple = (1,2,3,4)
  a = myTuple[0]
  b = myTuple[2]
  </code></pre>
  <p>Or something like</p>
  <pre><code>(a,_,b,_) = myTuple
  </code></pre>
  <p>Is there a way I could unpack the values, but ignore one or more of them of them?</p>
