python KeyError，找不到錯誤

Question

import json 
import pandas as pd 

data = """ 
{ 
    "name": "Wes", 
    "place_lived": ["United Stats", "Spain", "Germany"], 
    "pet": null, 
    "Siblings": [ 
     {"name": "Scott", "age": 25, "pet": "Zuko"}, 
     {"name": "Katie", "age": 33, "pet": "Cisco"}] 
} 
""" 

result = json.loads(data) 
df = pd.DataFrame(result['siblings'], columns=['name', 'age']) 
print(df) 

我從「Python for Data Analysis」一書中得到了這個例子，我得到的只是keyerror，我不知道錯誤在哪裏。

可能是最簡單的答案了。注意區分大小寫。

import json 
import pandas as pd 

data = """ 
{ 
    "name": "Wes", 
    "place_lived": ["United Stats", "Spain", "Germany"], 
    "pet": null, 
    "Siblings": [ 
     {"name": "Scott", "age": 25, "pet": "Zuko"}, 
     {"name": "Katie", "age": 33, "pet": "Cisco"}] 
} 
""" 

result = json.loads(data) 
df = pd.DataFrame(result['Siblings'], columns=['name', 'age']) 
print(df)
