我從api密鑰獲取json。

這是我的json:{'[{"count":27,"stem":"obama","term":"obama"},

{"count":20,"stem":"boehner","term":"boehner"},

{"count":4,"stem":"tax","term":"tax"},

{"count":3,"stem":"daley","term":"daley"},

{"count":3,"stem":"couldn","term":"couldn"},

{"count":2,"stem":"formul","term":"formulation"}

]' : ' '}

我想從這個json中得到前5個值。我把這個翻到字典列表：

^{pr2}$

所有代碼如下：import urllib2, mediacloud, json,itertools,ast

from collections import Counter

webUrl = urllib2.urlopen("https://api.mediacloud.org/api/v2/wc/list?q=obama+AND+media_id:1&stats=1&&fq=publish_date:%5B2012-04-01T00:00:00.000Z+TO+2012-04-01T00:00:00.000Z%5D&key= ")

def changetodict(data):

json_str = ast.literal_eval(json.dumps(data))

#common = json.loads(json_str)

commonDict = dict(itertools.izip_longest(*[iter(json_str)] * 2, fillvalue=""))

print commonDict

most_common_imdb_value = Counter(b['key'] for b in commonDict).most_common(1)[0]

if(webUrl.getcode()== 200):

data = webUrl.readlines()

changetodict(data)

else:

print "error"

我需要做些什么才能讓它生效？在
