从json字典中检索值+ python

这个特殊的问题经常被问到安静，我真的尝试过所有不同的方法，没有任何运气。从json字典中检索值+ python

这是我的json response.And Im试图检索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" 
     } 
    } 
    ] 
}

我能够用下面的代码

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)

输出

(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'Asian') 
(u'cuisine_id', 3) 
(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_name', u'Cafe')

(u'cuisine_name', u'Fast Food') 
(u'cuisine_id', 40) 
(u'cuisine_name', u'Finger Food') 
(u'cuisine_id', 271) 
(u'cuisine_name', u'Ice Cream') 
(u'cuisine_id', 233) 
(u'cuisine_name', u'Italian') 
(u'cuisine_id', 55) 
(u'cuisine_name', u'Juices')

(u'cuisine_name', u'Pizza') 
(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)

得到美食的数据，但是，我想要的是像90不同的值，街头食品。我将如何实现它？

有没有其他办法？

继变化让我

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']

试着用'打印更换内部的循环（名单（项目[“美食”]。值（）））' – Kendas

尝试：

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

你缺少右括号 –

感谢@DanIonescu编辑的解决方案。 – JkShaw

谢谢@jyotish –

我想回答下面的错误

TypeError: string indices must be integers

这应该修正这个错误

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