title: Python - get key in nested dictionary
body: <p>I know how to index and retrieve almost every item in the following <code>dict</code>:</p>
  
  <pre><code>playlists={'user':[
                 {'playlist':{
                      'tracks': [        
                      {'name': 'Karma Police','artist': 'Radiohead', 'count': "1.0"},
                      {'name': 'Bitter Sweet Symphony','artist': 'The Verve','count': "2.0"}                    
                       ]
                     }
                  }
                ]
              }
  </code></pre>
  
  <p>except: how do I print the <code>string 'playlist'</code> using <code>key/value</code>relation?</p>
