问题描述
我有如下所示的字典
d1:
{'teachers': 49,'students': 289,'R': 3.7,'holidays': 165,'Em': {'from': '2020-02-29T20:00:00.000Z','to': '2020-03-20T20:00:00.000Z','F': 3,'C': 2},'OS':18
'sC': {'from': '2020-03-31T20:00:00.000Z','to': '2020-05-29T20:00:00.000Z','F': 25,'C': 31}}
我想将上面的字典转换为数据框,如下面的熊猫所示。
teachers students R holidays Em_from Em_to Exam_F Exam_C OS sC_from sC_to sC_F sC_C
49 289 3.7 165 2020-02-29 2020-03-20 3 2 18 2020-03-31 2020-05-29 25 31
解决方法
您可能正在寻找pandas.json_normalize
:
d = {'teachers': 49,'students': 289,'R': 3.7,'holidays': 165,'Em': {'from': '2020-02-29T20:00:00.000Z','to': '2020-03-20T20:00:00.000Z','F': 3,'C': 2},'OS':18,'sC': {'from': '2020-03-31T20:00:00.000Z','to': '2020-05-29T20:00:00.000Z','F': 25,'C': 31}}
print(pd.json_normalize(d,sep='_'))
打印:
teachers students R ... sC_to sC_F sC_C
0 49 289 3.7 ... 2020-05-29T20:00:00.000Z 25 31
