從json字典中檢索值+ python

這個特殊的問題經常被問到安靜，我真的嘗試過所有不同的方法，沒有任何運氣。從json字典中檢索值+ python

這是我的json response.And Im試圖檢索cuisine_id和cuisine_name字段的值。

{ 
    "cuisines": [ 
    { 
     "cuisine": { 
     "cuisine_id": 1, 
     "cuisine_name": "American" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 2, 
     "cuisine_name": "Andhra" 
     } 
    }, 
    {

     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 270, 
     "cuisine_name": "Beverages" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 7, 
     "cuisine_name": "Biryani" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 168, 
     "cuisine_name": "Burger" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 30, 
     "cuisine_name": "Cafe" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 25, 
     "cuisine_name": "Chinese" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 35, 
     "cuisine_name": "Continental" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 100, 
     "cuisine_name": "Desserts" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 38, 
     "cuisine_name": "European" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 40, 
     "cuisine_name": "Fast Food" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 271, 
     "cuisine_name": "Finger Food" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 233, 
     "cuisine_name": "Ice Cream" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 55, 
     "cuisine_name": "Italian" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 164, 
     "cuisine_name": "Juices" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 62, 
     "cuisine_name": "Kerala" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 66, 
     "cuisine_name": "Lebanese" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 72, 
     "cuisine_name": "Mangalorean" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 75, 
     "cuisine_name": "Mughlai" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 50, 
     "cuisine_name": "North Indian" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 82, 
     "cuisine_name": "Pizza" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 1005, 
     "cuisine_name": "Roast Chicken" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 83, 
     "cuisine_name": "Seafood" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 85, 
     "cuisine_name": "South Indian" 
     } 
    }, 
    { 
     "cuisine": { 
     "cuisine_id": 90, 
     "cuisine_name": "Street Food" 
     } 
    } 
    ] 
}

我能夠用下面的代碼

import requests 
from pprint import pprint 
import json 




apiUrl = "https://<blahblah>/api/v2.1/cuisines?city_id=31" 
header = {"User-agent":"curl/7.43.0", "Accept":"application/json","user-key":"API_KEY"} 

response = requests.get(apiUrl, headers=header) 

binary = response.content 
data = json.loads(binary) 


for item in data['cuisines']: 
    #print "item is" + str(item) 
    for k,v in item['cuisine'].items(): 
     print(k,v)

輸出

(u'cuisine_name', u'American') 
(u'cuisine_id', 1) 
(u'cuisine_name', u'Andhra') 
(u'cuisine_id', 2) 
(u'cuisine_name', u'Arabian')

(u'cuisine_name', u'Bakery') 
(u'cuisine_id', 5) 
(u'cuisine_name', u'Beverages') 
(u'cuisine_id', 270) 
(u'cuisine_name', u'Biryani') 
(u'cuisine_id', 7) 
(u'cuisine_name', u'Burger') 
(u'cuisine_id', 168)

(u'cuisine_id', 40) 
(u'cuisine_name', u'Finger Food') 
(u'cuisine_id', 271)

(u'cuisine_id', 82) 
(u'cuisine_name', u'Roast Chicken') 
(u'cuisine_id', 1005) 
(u'cuisine_name', u'Seafood') 
(u'cuisine_id', 83) 
(u'cuisine_name', u'South Indian') 
(u'cuisine_id', 85) 
(u'cuisine_name', u'Street Food') 
(u'cuisine_id', 90)

得到美食的數據，但是，我想要的是像90不同的值，街頭食品。我將如何實現它？

有沒有其他辦法？

繼變化讓我

TypeError: string indices must be integers

for item in data['cuisines']: 
    #print "item is" + str(item) 
    for ditem in item['cuisine']: 
     print ditem['cuisine_name'] 
     print ditem['cuisine_id']

試着用'打印更換內部的循環（名單（項目[「美食」]。值（）））' – Kendas

嘗試：

for item in data['cuisines']: 
    for k,v in item.items(): 
    print('{}, {}'.format(v['cuisine_id'], v['cuisine_name']))

你缺少右括號 –

感謝@DanIonescu編輯的解決方案。 – JkShaw

謝謝@jyotish –

for item in data['cuisines']: 
    print(*item['cuisine'].values(),sep=', ')

我想回答下面的錯誤

TypeError: string indices must be integers

這應該修正這個錯誤

for item in data['cuisines']: 
    for ditem in item: 
     print item[ditem]['cuisine_name'] 
     print item[ditem]['cuisine_id']
