title: python get second value of a tuple in a list
body: <p>i have following list: <code>parent_child_list</code> with id-tuples:</p>
  
  <pre><code>[(960, 965), (960, 988), (359, 364), (359, 365), 
  (361, 366), (361, 367), (361, 368), (361, 369), 
  (360, 370), (360, 371), (360, 372), (360, 373), (361, 374)]
  </code></pre>
  
  <p>Example: i would like to print those values which are combined with the id 960. Those would be: 965, 988</p>
  
  <p>I tried to convert the list into a dict:</p>
  
  <pre><code>rs = dict(parent_child_list)
  </code></pre>
  
  <p>Because now i could simply say:</p>
  
  <pre><code>print rs[960]
  </code></pre>
  
  <p>But unfortunately i forgot that dict cannot have double values so instead of getting 965, 988 as the answer i receive only 965.</p>
  
  <p>Is there any easy option to keep the double values?</p>
  
  <p>Many thanks</p>
