使用相同的键值从json文件中提取数据帧

Question

我有一个json文件（如下所示），我需要在配置文件数据帧，其列名为“jive_label”的值> []和值作为其值，预期输出如下。我也给了示例代码，我尝试只打印一列，但该代码显然无效。

import requests
import pandas as pd
import numpy as np
from pandas.io.json import json_normalize
import sys
import json


r=requests.get(url,data=payload,headers=headers,params=querystring,verify=False)
json_data=r.json()
df=pd.DataFrame([])
    for i in json_data.get('profile',[]):
        if i.get('jive_label')=='Title':

            dfDict={'Title': i.get('value')
                   }
         df=df.append(pd.DataFrame(dfDICT,index=[0]),ignore_index=True)
    print(df.head())*

预期输出：

Answer 1

使用以下代码：

import json
import pandas as pd

with open('data.json') as fd:
    data = json.load(fd)

profile = data['jive']['profile']
headers = [e['jive_label'] for e in profile]
values  = [e['value']      for e in profile]

df = pd.DataFrame(columns=headers, data=[values])

Answer 2

使用pandas from_dict是解决此问题的一种方法：

# normalize your dict and drop unwanted fields
data = pd.DataFrame.from_dict(myjson['jive']['profile']).drop(['jive_displayOrder','jive_showSummaryLabel'], axis=1)

# reshape the data
data = pd.pivot_table(data, index=None, columns='jive_label', values='value', aggfunc='max')

# remove unwanted names
data.columns.name = None
data.reset_index(drop=True)

print(data)
