title: for loop iterate tuples
body: <p>I'm a beginner in Python (and going back to coding after 20 years...)</p>
  
  <p>I'm doing a small script in order to learn irregular english verbs. 
  I create my dict which look like this (it's in french)</p>
  
  <pre><code>verbes = {
  "abide":["abode","abode","respecter / se conformer à"],
  "arise":["arisen","arisen","survenir"],
  }
  </code></pre>
  
  <p>if i want to iterate the verbes i'm doing that for exemple:</p>
  
  <pre><code>for verb, (pret, past, trad) in verbes.items():
      print "Le verbe %s se conjugue au prétérit par %s, au participe passé par %s et se traduit par %s" % (verb, pret, past, trad)
  </code></pre>
  
  <p>Ok that works. 
  Then i found out i can import random to pick up one random key and value in my dictionnary</p>
  
  <pre><code>rand = random.choice(verbes.items())
  </code></pre>
  
  <p>If i print rand i have a key, value
  but if i iterate again i have a traceback:</p>
  
  <pre><code>Traceback (most recent call last):
  File ".\exverbe1.py", line 209, in &lt;module&gt;
      for verb, (pret, past, trad) in rand.items(): AttributeError: 'tuple' object has no attribute 'items'
  </code></pre>
  
  <p>I'm not yet at the "tuple" lesson but i've tried to turn it into a list, a dict, etc. without success. I looked over "for loop tuple" in stackoverflow without result. So now i'm asking for help after 3 hours trying to figure it out...
  Thanks </p>
