title: How can I print out specific key values from nested dict?
body: <p>I have some address list with nested dict type like this.</p>
  <pre><code>{   'documents': [   {   'address': {   'address_name': '100 Broadway, New York, NY 10005',
                                      'main_address_no': '10005',
                                      'mountain_yn': 'N',
                                      'region_1depth_name': 'New York',
                                      'region_2depth_name': 'Broadway',
                                      'region_3depth_name': '100',
                                      'sub_address_no': '',
                                      'zip_code': ''},
                       'road_address': None}],
  'meta': {'total_count': 1}}
  </code></pre>
  <p>and I wonder how can I print out specific value like 'address_name'.
  I've tried to access with indexing method, but it won't work</p>
