import pandas as pd myDict = {'a':1,'b':2} print("【显示】myDict =", myDict) print("【执行】pd.json_normalize(myDict)") print(pd.json_normalize(myDict)) A选项:myDict是字典 B选项:执行后的结果是数据框 C选项:这个函数可以将字典数据转换为数据框 ...
有时候可能会需要这样的功能:把任意深度的嵌套列表扁平化,例如把[1, 2, [3, [4]]]和[1, [2,...
您输入的record_path错误,应为['Report Details', 'report Accessible']。
json_normalize()用于平铺字典(删除嵌套),因为JSON状态对象已经是平铺的,所以不需要这样做。用pd。如果...
students部分的数据并未被成功解析,此时可以为record_path设置值即可,调用方式为pd.json_normalize(json_obj, record_path='students'),在此调用方式下,得到的结果只包含了name部分的数据。 若要增加其他字段的信息,则需为meta参数赋值,例如下述调用方式下,得到的结果如下: pd.json_normalize(json_obj, record_path...
record_path is not None, meta is not None: normalize record_path and meta. record_path is None, meta is not None: normalize only meta. [My request] Alternative Solutions The alternative solution is to use pd.json_normalize to create the dataframe then select desired columns: result = pd....
