Question

我只需要最后一个数字25，所以我可以将它改为int（）。我有这个文本文件：

{
  "members": [
    {"name": "John", "location": "QC", "age": 25},
    {"name": "Jesse", "location": "PQ", "age": 24},
}

然后返回年龄

的值

这是我到目前为止所尝试过的，所以我很困惑......我用什么样的函数来解析它？这就是你所说的吗？我是编程和python的新手。

import json
import pprint

my_data = json.loads(open("team.json.txt").read())

print 'members whose location is in PQ'
member_in_pq = [member for member in my_data['members'] \
    if member['location'] == 'PQ']
pprint.pprint(member_in_pq)

顺便说一句，我尝试了这段代码，但却出错了：

result = my_data.split(':')[-1]

我不确定你问的是怎么做，但会尝试猜测。

首先，您显示的文本不是有效的JSON，需要更改为以下内容：

{                                                  
  "members": [                                     
    {"name": "John", "location": "QC", "age": 25}, 
    {"name": "Jesse", "location": "PQ", "age": 24}
  ]
}

这里可以打印出位置PQ中每位成员的所有数据：

import json
import pprint

my_data = json.loads(open("team.json.txt").read())

members_in_pq = [member for member in my_data['members']
                    if member['location'] == 'PQ']

print 'members whose location is in PQ'
for member in members_in_pq:
    print '  name: {name}, location: {location}, age: {age}'.format(**member)

输出：

members whose location is in PQ
  name: Jesse, location: PQ, age: 24

从python
