Question

我需要连接并从API获取数据（数据将采用JSON格式），然后以表格的形式存储数据。我使用python以JSON形式提取数据但现在当我以.csv格式转换它时，我得到错误为：TypeError：list indices必须是整数，而不是str。

我使用的代码如下：

import urllib2
import json
import csv
f = urllib2.urlopen('https://api.weather.com/v1/location/KORD:9:US/observations/historical.json?units=e&startDate=20140703&endDate=20140704&apiKey=742a31ced27a477045')
json_string = f.read()
x = json.loads(json_string)
f = csv.writer(open("test.csv", "wb+"))

# For CSV Headers
f.writerow(["obs_id", "obs_name", "temp", "valid_time_gmt"])
for x in x:
    f.writerow([x["observations"]["obs_id"],
                x["observations"]["obs_name"],
                x["observations"]["temp"],
               x["observations"]["valid_time_gmt"]])

f.close()

提取的JSON就像

> {   "metadata": {
>     "language": "en-US",
>     "transaction_id": "1484310885350:-90975020",

>     "location_id": "KORD:9:US",
>     "units": "e",
>     "expire_time_gmt": 1484314485,
>     "status_code": 200   },   "observations": [
>     {
>       "key": "KORD",
>       "obs_id": "KORD",
>       "obs_name": "Chicago/O'Hare",
>       "valid_time_gmt": 1404453060,
>       "day_ind": "N",
>       "temp": 61
>     },
>     {
>       "key": "KORD",
>       "obs_id": "KORD",
>       "obs_name": "Chicago/O'Hare",
>       "valid_time_gmt": 1404456660,
>       "day_ind": "N",
>       "temp": 60
>     },....... and so on

请你帮忙解决一下需要改变的地方吗？

从API（JSON形式的数据）连接加载数据并存储在表中
