title: Adding dictionary values to a list?
body: <p>I have the following:</p>
  
  <pre><code> list_of_values = []    
   x = { 'key1': 1, 'key2': 2, 'key3': 3 }
  </code></pre>
  
  <p>How can I iterate through the dictionary and append one of those values into that list? What if I only want to append the value of 'key2'.</p>
