如何格式化Json查詢結果

Question

#!/usr/bin/env python
import urllib2
import json
api_key = 'VtxgIC2UnhfUmXe_pBksov7-lguAQMZD'
url = 'http://www.energyhive.com/mobile_proxy/getCurrentValuesSummary?token='+api_key
response = urllib2.urlopen(url)
content = response.read()
for x in json.loads(content):
    if x["cid"] == "PWER":
        print (x["data"])
for y in json.loads(content):
    if y["cid"] == "PWER_GAC":
        print(y["data"])
for z in json.loads(content):
    if z["cid"] == "PWER_IMM":
        print(z["data"])
for a in json.loads(content):
    if a["cid"] == "FBAK_IMM":
        print(a["data"])

當我運行代碼時，我會得到這種格式的結果

[{u'1439193214000': 2880}]
[{u'1439193214000': 2979}]
[{u'1439193212000': 3276}]
[{u'1439193212000': 135}]

我如何刪除所有內容，而只在以下數字后打印：

Answer 1

json.loads將其轉換為python結構，在這種情況下為字典列表，因此只需調用values函數

    import urllib2
    import json
    api_key = 'VtxgIC2UnhfUmXe_pBksov7-lguAQMZD'
    url = 'http://www.energyhive.com/mobile_proxy/getCurrentValuesSummary?token='+api_key
    response = urllib2.urlopen(url)
    content = response.read()
    for x in json.loads(content):
        if x["cid"] == "PWER":
            print (x["data"][0].values()[0])
