title: Loading numbers from Python dictionary
body: <p>I am trying to work this out by using a dictionary that has two different details:</p>
  
  <pre><code>direc = {}
  
  a = 17
  b = 165
  direc.update({a: b})
  
  a = 19
  b = 174
  direc.update({a: b})
  
  for x,y in direc:
      print('age:' +str(x) + ' and height :'+str(y))
  </code></pre>
  
  <p>I need the output to be:</p>
  
  <pre><code>age:17 and height:165
  age:19 and height:174
  </code></pre>
