從冒號後的文本文件或python冒號之前獲取值

Question

我只需要最後一個數字25，所以我可以將其更改爲int（）。我有這個文本文件：

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

然後返回

這是我迄今爲止嘗試過，所以我如此堅持...什麼樣的功能，我用它來解析它的時代價值？這就是你所說的嗎？我是編程和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) 

順便說一句我試過這個代碼，但它給出了一個錯誤：

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

我不知道你問怎麼辦，反而會使試圖猜測。

首先，你顯示文本不是有效的JSON和需要改變的東西是這樣的：

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

這裏的東西，將打印出所有的數據，每個成員的位置PQ ：

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) 

輸出：

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