Python 如何将这种列形式的嵌套JSON转换为数据帧

我可以将这种列格式的嵌套JSON格式读入pandas

JSON格式

Python脚本 更新 我想将下面的JSON方案转换为表格格式，如表所示，如何

JSON方案 Pandas有一个功能（从0.13开始），直接来自文档：

In [205]: from pandas.io.json import json_normalize

In [206]: data = [{'state': 'Florida',
   .....:           'shortname': 'FL',
   .....:           'info': {
   .....:                'governor': 'Rick Scott'
   .....:           },
   .....:           'counties': [{'name': 'Dade', 'population': 12345},
   .....:                       {'name': 'Broward', 'population': 40000},
   .....:                       {'name': 'Palm Beach', 'population': 60000}]},
   .....:          {'state': 'Ohio',
   .....:           'shortname': 'OH',
   .....:           'info': {
   .....:                'governor': 'John Kasich'
   .....:           },
   .....:           'counties': [{'name': 'Summit', 'population': 1234},
   .....:                        {'name': 'Cuyahoga', 'population': 1337}]}]
   .....: 

In [207]: json_normalize(data, 'counties', ['state', 'shortname', ['info', 'governor']])
Out[207]: 
         name  population info.governor    state shortname
0        Dade       12345    Rick Scott  Florida        FL
1     Broward       40000    Rick Scott  Florida        FL
2  Palm Beach       60000    Rick Scott  Florida        FL

也许这就是你要找的？我总是忘记它的存在，所以我重新实现了几次-（@DSM我也是…公平地说，这是“最近的”。：）@Yhayden谢谢你的回答，你能给我一些新问题的提示吗@Andy Hayden如果

'countries'

是

'info'

的孩子呢？元是什么？我仍然在测试如何解析

'info'：['countries']

值。
