title: Iterating through list which is value of a dict
body: <p>I have many sets of JSON data, each of which looks like this after being converted into dict:</p>
  <pre><code>json_data = 
  {
    &quot;root&quot;:[
      1,
      2,
      3
    ]
  }
  </code></pre>
  <p>I want to iterate through the list <code>[1,2,3]</code> with this:</p>
  <pre><code>for value in json_data.values():
      print(value)
  </code></pre>
  <p>I expect to get this output:</p>
  <p><code>1</code>
  <code>2</code>
  <code>3</code>
  But I get this :</p>
  <p><code>[1,2,3]</code></p>
  <p>What should I change in the code? Thanks !</p>
