如何在这个字典中只获取中间嵌套键？

我有以下字典：

  1. {'AK': {'AK0010100': {'agency_name': 'Anchorage Police Department',
  2.    'agency_type_name': 'City',
  3.    'county_name': 'ANCHORAGE',
  4.    'division_name': 'Pacific',
  5.    'latitude': 61.17425,
  6.    'longitude': -149.284329,
  7.    'nibrs': False,
  8.    'nibrs_start_date': None,
  9.    'ori': 'AK0010100',
  10.    'region_desc': 'Region IV',
  11.    'region_name': 'West',
  12.    'state_abbr': 'AK',
  13.    'state_name': 'Alaska'},
  14.   'AK0010200': {'agency_name': 'Fairbanks Police Department',
  15.    'agency_type_name': 'City',
  16.    'county_name': 'FAIRBANKS NORTH STAR',
  17.    'division_name': 'Pacific',
  18.    'latitude': 64.83945,
  19.    'longitude': -147.71942,
  20.    'nibrs': False,
  21.    'nibrs_start_date': None,
  22.    'ori': 'AK0010200',
  23.    'region_desc': 'Region IV',
  24.    'region_name': 'West',
  25.    'state_abbr': 'AK',
  26.    'state_name': 'Alaska'}}}

而我只需要辅助键（例如“ak0010100”）。我尝试了以下代码：

  1. for keys, values in cities.items():
  2.   for values in keys:
  3.     print(keys[values])

但这似乎不起作用。我对python还比较陌生，所以如果有任何帮助，我将不胜感激。提前谢谢！

要获取辅助密钥，请执行以下操作：

  1. dct = {
  2.     "AK": {
  3.         "AK0010100": {
  4.             "agency_name": "Anchorage Police Department",
  5.             "agency_type_name": "City",
  6.             "county_name": "ANCHORAGE",
  7.             "division_name": "Pacific",
  8.             "latitude": 61.17425,
  9.             "longitude": -149.284329,
  10.             "nibrs": False,
  11.             "nibrs_start_date": None,
  12.             "ori": "AK0010100",
  13.             "region_desc": "Region IV",
  14.             "region_name": "West",
  15.             "state_abbr": "AK",
  16.             "state_name": "Alaska",
  17.         },
  18.         "AK0010200": {
  19.             "agency_name": "Fairbanks Police Department",
  20.             "agency_type_name": "City",
  21.             "county_name": "FAIRBANKS NORTH STAR",
  22.             "division_name": "Pacific",
  23.             "latitude": 64.83945,
  24.             "longitude": -147.71942,
  25.             "nibrs": False,
  26.             "nibrs_start_date": None,
  27.             "ori": "AK0010200",
  28.             "region_desc": "Region IV",
  29.             "region_name": "West",
  30.             "state_abbr": "AK",
  31.             "state_name": "Alaska",
  32.         },
  33.     }
  34. }
  36. keys = [k for d in dct.values() for k in d]
  37. print(keys)

印刷品：

  1. ['AK0010100', 'AK0010200']
