我正在尝试解析我收到的 json 数据

    {'results': [{'address_components': [{'long_name': 'New York',

   {
      "lat": 40.7902778, 
      "lng": -73.9597222
   }
]

例如，我如何能够解析“结果”？我想打印出结果中的所有数据。我的代码是...

import urllib, json
import pprint

URL2 = "http://maps.googleapis.com/maps/api/geocode/json?address=New+York&sensor=false"

googleResponse = urllib.urlopen(URL2)
jsonResponse = json.loads(googleResponse.read())
pprint.pprint(jsonResponse)
test = json.dumps([s['geometry']['location'] for s in jsonResponse['results']], indent=3)
print test['results']

我得到的错误是

回溯（最近一次通话最后）：

文件“C:/Python27/jstox.py”，第 10 行，在

打印测试['结果']

TypeError：字符串索引必须是整数，而不是 str

你实际上已经得到了你想要的结果。

import urllib, json
import pprint

URL2 = "http://maps.googleapis.com/maps/api/geocode/json?address=New+York&sensor=false"

googleResponse = urllib.urlopen(URL2)
jsonResponse = json.loads(googleResponse.read())
pprint.pprint(jsonResponse)
pprint.pprint(jsonResponse['results'])

如果您熟悉这些，在这种情况下，可以将 json 数据与 Python字典类似地处理。
