python - 使用 Python 解析用户个人资料数据的 Twitter API JSON 输出时出现问题

Question

我认为另一个SO线程会回答我的问题(http://stackoverflow.com/questions/4883751/trouble-reading-json-object-in-python)，因为它与我的问题非常相似，但是那里的数据与我的案例中的数据略有不同。

我从 Twitter API 中提取了大约 470 条记录来获取 Twitter 用户数据，例如:

{
steve: {
follow_request_sent: false,
profile_use_background_image: true,
default_profile_image: false,
geo_enabled: true,

contributors_enabled: false,
time_zone: "Central Time (US & Canada)",
protected: false,
default_profile: false,
following: false
},
}

问题是每条记录都以该人的 Twitter 句柄开头，因此每条记录都是不同的。所以我只能使用:

import json
import csv

f = open('my.json')
data = json.load(f)
f.close()

for item in data:
    print item

打印出这些句柄，但不知道如何在没有 key 的情况下进入每个人的记录。

我在这里严重忽略了什么？我至少想获取“描述”，它作为键嵌套在用户名中。

也许我缺少您正在寻找的东西，但您不能这样做:

import json

f = open('my.json')  
data = json.load(f)
f.close()

for key in data.keys():
    print data[key]["description"]
