我正在使用中给出的示例json_normalize
此处给出的文档pandas.json_normalize — pandas 1.0.3 文档,不幸的是,我无法粘贴我的实际 JSON,但这个示例有效。从文档粘贴:
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}]}]
result = json_normalize(data, 'counties', ['state', 'shortname',
['info', 'governor']])
result
name population state shortname info.governor
0 Dade 12345 Florida FL Rick Scott
1 Broward 40000 Florida FL Rick Scott
2 Palm Beach 60000 Florida FL Rick Scott
3 Summit 1234 Ohio OH John Kasich
4 Cuyahoga 1337 Ohio OH John Kasich
如果 JSON 是下面的 JSON 呢?info
是一个数组而不是一个字典:
data = [{'state': 'Florida',
'shortname': 'FL',
'info': [{'governor': 'Rick Scott'},
{'governor': 'Rick Scott 2'}],
'counties': [{'name': 'Dade', 'population': 12345},
{'name': 'Broward', 'population': 40000},
{'name': 'Palm Beach', 'population': 60000}]},
{'state': 'Ohio',
'shortname': 'OH',
'info': [{'governor': 'John Kasich'},
{'governor': 'John Kasich 2'}],
'counties': [{'name': 'Summit', 'population': 1234},
{'name': 'Cuyahoga', 'population': 1337}]}]
您如何使用以下输出获得json_normalize
:
name population state shortname info.governor
0 Dade 12345 Florida FL Rick Scott
1 Dade 12345 Florida FL Rick Scott 2
2 Broward 40000 Florida FL Rick Scott
3 Broward 40000 Florida FL Rick Scott 2
4 Palm Beach 60000 Florida FL Rick Scott
5 Palm Beach 60000 Florida FL Rick Scott 2
6 Summit 1234 Ohio OH John Kasich
7 Summit 1234 Ohio OH John Kasich 2
8 Cuyahoga 1337 Ohio OH John Kasich
9 Cuyahoga 1337 Ohio OH John Kasich 2
或者如果有其他方法可以做到这一点,请告诉我。
