title: Parse output from json python
body: <p>I have a json below, and I want to parse out value from this dict.</p>
  <p>I can do something like this to get one specific value</p>
  <pre><code>print(abc['everything']['A']['1']['tree']['value'])
  </code></pre>
  <p>But, what is best way to parse out all &quot;value?&quot;
  I want to output good, bad, good.</p>
  <pre><code>   abc = {'everything': {'A': {'1': {'tree': {'value': 'good'}}}, 
  
  'B': {'5': {'tree1': {'value': 'bad'}}},
  
  'C': {'30': {'tree2': {'value': 'good'}}}}}
  </code></pre>
