title: How to compare two lists in the same dictionary and see if a value is in both
body: <p>I am fairly new to Python and would appreciate some help for a project I am working on for work.<br>
  I have a dictionary of lists and want to traverse the dictionary and check if any values of the lists are the same.  </p>
  
  <pre><code>dict={'one':[1,2,3], 'two':[3,4,5], 'three':[5,6,7]}
  </code></pre>
  
  <p>I need to check the list value of 'one' and check to see if in 'two' and 'three', then check 'two' values are in 'three' and so on.  Then I need to print out the key and values that are the same.
  ie.</p>
  
  <pre><code>3 - 'one' 'two'
  5 - 'two' 'three'
  </code></pre>
  
  <p>Not sure the best way to do this.</p>
