我有以下Python代码来读取JSON文件：
import json
from pprint import pprint
with open('traveladvisory.json') as json_data:
print 'json data ',json_data
d = json.load(json_data)
json_data.close()
以下是“traveladvisory.json”的一部分。使用此代码打开文件。变量＆＃39; d＆＃39;会打印出所有JSON数据。但我似乎无法正确阅读所有“乡村英语”的语法。和＆＃39;咨询文本＆＃39;字段及其数据并打印出来。有人可以帮忙吗？这是json数据的一部分（对不起，不能打印出来）：

答案 0 :(得分：0)
这对我有用：
for item in d['data']:
print d['data'][item]['country-eng'], d['data'][item]['eng']['advisory-text']
答案 1 :(得分：0)
假设d包含json数据
for country in d["data"]:
print "Country :",country
#country.get() gets the value of the key . the second argument is
#the value returned in case the key is not present
print "country-eng : ",country.get("country-eng",0)
print "advisory-text(eng) :",country["eng"].get("advisory-text",0)
print "advisory-text(fra) :",country["fra"].get("advisory-text",0)
答案 2 :(得分：0)
如果我理解你的问题。以下是如何做到这一点：
import json
with open('traveladvisory.json') as json_data:
d = json.load(json_data)
# print(json.dumps(d, indent=4)) # pretty-print data read
for country in d['data']:
print(country)
print(' country-eng: {}'.format(d['data'][country]['country-eng']))
print(' advisory-state: {}'.format(d['data'][country]['advisory-state']))
输出：
DZ
country-eng: Algeria
advisory-state: 1
AL
country-eng: Albania
advisory-state: 0
AF
country-eng: Afghanistan
advisory-state: 3
答案 3 :(得分：0)
然后代码下面的python2工作（如果你需要python3版本请问） 您必须使用load 模块
中的json功能#-*- coding: utf-8 -*-
import json # import the module we need
with open("traveladvisory.json") as f: # f for file
d = json.load(f) # d is a dictionnary
for key in d['data']:
print d['data'][key]['country-eng']
print d['data'][key]['eng']['advisory-text']
在处理文件对象时，最好使用 with 语句。 这样做的好处是文件在套件完成后正确关闭，即使在途中引发了异常。
此外，json是错误的，您必须从第98行删除逗号：
