title: Python -Intersection of multiple lists?
body: <p>I am playing with python and am able to get the intersection of two lists:</p>
  
  <pre><code>result = set(a).intersection(b)
  </code></pre>
  
  <p>Now if <code>d</code> is a list containing <code>a</code> and <code>b</code> and a third element <code>c</code>, is there an built-in function for finding the intersection of all the three lists inside <code>d</code>? So for instance,</p>
  
  <pre><code>d = [[1,2,3,4], [2,3,4], [3,4,5,6,7]]
  </code></pre>
  
  <p>then the result should be</p>
  
  <pre><code>[3,4]
  </code></pre>
