我試圖打造出了從我的數據框中一個JSON文件,該文件類似於這樣:格式化JSON
{'249' : [
{'candidateId': 751,
'votes':7528,
'vote_pct':0.132
},
{'candidateId': 803,
'votes':7771,
'vote_pct':0.138
}...
],
'274': [
{'candidateId': 891,
....
我的數據框看起來是這樣的:
officeId candidateId votes vote_pct
0 249 751 7528 0.132198
1 249 803 7771 0.136465
2 249 818 7569 0.132918
3 249 827 9089 0.159610
4 249 856 2271 0.039881
5 249 877 7491 0.131548
6 249 878 8758 0.153798
7 249 895 6267 0.110054
8 249 1161 201 0.003530
9 274 736 4664 0.073833
10 274 737 6270 0.099256
11 274 757 4953 0.078407
12 274 769 5239 0.082935
13 274 770 7134 0.112933
14 274 783 7673 0.121466
15 274 862 6361 0.100697
16 274 901 7671 0.121434
使用功能我可以翻轉數據幀的指數,並返回它作爲一個JSON字符串爲每個辦公室的ID,像這樣:
def clean_results(votes):
#trying to get a well structured json file
return votes.reset_index().to_json(orient='index', double_precision=2)
res_json = results.groupby(['officeId']).apply(clean_results)
但是,當我這樣做,我結束ü p與新的數據幀,與一個JSON對象爲每個officeID和JSON使用編號索引作爲頂層,像這樣:
{"0":{"index":0.0,"officeId":249.0,"candidateId":751.0,"total_votes":7528.0,"vote_pct":0.13},"1":{"index":1.0,"officeId":249.0,"candidateId":803.0,"total_votes":7771.0,"vote_pct":0.14},"2":...
