我正在尝试将从 facebook 的图形 API 返回的 json 解析写入 csv，并且当字典在列表中时无法获取键的值。我使用的代码如下：

import json
import csv
import urllib
import win32com.client

# Start Excel
xlApp = win32com.client.Dispatch( "Excel.Application" )
workbook = xlApp.Workbooks.Open( 'C:\AAAA - Report\WWWWorkflow\IO listcsv.xlsm' )
sheet = workbook.Sheets( 'Sheet1' )
sheet.Activate( )

# Get values
spam = sheet.Cells( 2, 2 ).Value

default = 'none'
Ad_account_id = spam
target_url = "https://graph.facebook.com/act_" + Ad_account_id + "/adgroups?fields=id,targeting&limit=10000&access_token=blah"
json_data = urllib.urlopen(target_url)
data = json.load(json_data)
data = data["data"]
f=csv.writer(open('C:/AAAA - Report/WWWWorkflow/adid.csv','wb+'))
f.writerow(["id", "country", "age max", "keywords", "BCT"])

# the .get helps in tackling the keyerror which is when a value is missing in page type, etc.

delimiter = ', '
for item in data:
    f.writerow([item.get('id','none'), delimiter.join(item.get('targeting').get("countries","none")), item.get('targeting').get('age_max','none'), delimiter.join(item.get('targeting').get("keywords","none")).encode('utf-8'), delimiter.join([str(item) for item in item.get('targeting').get("user_adclusters",'none')])])

# Goodbye Excel
workbook.Save( )
workbook.Close( )
xlApp.Quit( )

我得到的示例 JSON 响应如下：

{
         "targeting": {
            "genders": [
               1
            ],
            "age_max": 65,
            "age_min": 25,
            "countries": [
               "NZ"
            ],
            "user_adclusters": [
               {
                  "id": "6004941354772",
                  "name": "Engaged Gamers - Casino"
               },
               {
                  "id": "6004948896772",
                  "name": "Virtual Goods - Engaged"
               },
               {
                  "id": "6004948896972",
                  "name": "Virtual Goods - Active"
               }
            ],
            "page_types": [
               "mobile"
            ],
            "user_os": [
               "iOS_ver_4.0_and_above"
            ]
         },
         "id": "6008104890350"
      },

谁能帮我只获得“user_adclusters”的名称，它是格式化的（即所有文本都存在u'？
