当我为这个JSON文件添加数据帧时，它看起来像这样：

我需要将“帖子”列中的刺伤数据框化。 我尝试了这段代码：

with open('test.json') as data_file:    
   d = json.loads(data_file.read())
df= pd.DataFrame(d[0]['posts'])
df

df仅带第一行的值或包含[84个网址]的索引[0] ，如下图所示：

我需要的：

有没有一种方法可以对所有索引中的字典进行Dataframe？

提前致谢！

Answer 1

我相信你需要json_normalize ：

import json
from pandas.io.json import json_normalize    

with open('test.json') as file:    
    j = json.load(file)  

df = json_normalize(j, 'posts', ['totalPostsAvailable','status'])
print (df)

Answer 2

不漂亮，但您可以尝试这样的操作（未经测试）：

df = pd.DataFrame(d[0]['posts'])

for i in range(1,len(d['posts'])):
        df1= pd.DataFrame(d.iloc[i]['posts'])
        df = pd.concat([df,df1])
