title: Iterating over dict values
body: <p>If i would like to iterate over dictionary values that are stored in a tuple.</p>
  
  <p>i need to return the object that hold the "CI" value, i assume that i will need some kind of a for loop :</p>
  
  <pre><code>z = {'x':(123,SE,2,1),'z':(124,CI,1,1)}
  for i, k in db.z:
      for k in db.z[i]:
          if k == 'CI':
              return db.z[k]
  </code></pre>
  
  <p>i am probably missing something here, a point of reference would be good.</p>
  
  <p>if there is a faster way doing so it would all so help greatly </p>
