使用Python解析数据以创建json数据对象

这是我从Google bigquery解析的数据:

作为Python新手,我真的不知道如何解析该数据以创建一个json对象,如下所示:

[

{'count': 200, 'year': 2008},

{'count': 240, 'year': 2010},

{'count': 290, 'year': 2009}

]

任何人都可以给我一些入门的提示吗?

[{u'v': u'the'}, {u'v': u'995'}, {u'v': u'1600'}]

在这个单词中'the'count是995和year1600。因此也是如此。

回答:

如果“ Z”是您的大词典,则在“响应”上您将获得所需的结构。

import json

response = []

for row in z['rows']:

for key, dict_list in row.iteritems():

count = dict_list[1]

year = dict_list[2]

response.append({'count': count['v'], 'year' : year['v']})

print json.dumps(response)

响应后,您将获得以下信息:

[{'count': u'995', 'year': u'1600'},

{'count': u'942', 'year': u'1607'},

{'count': u'937', 'year': u'1599'},

{'count': u'894', 'year': u'1598'},

{'count': u'848', 'year': u'1592'},

{'count': u'841', 'year': u'1590'},

{'count': u'786', 'year': u'1603'},

{'count': u'779', 'year': u'1609'},

{'count': u'762', 'year': u'1597'},

{'count': u'753', 'year': u'1594'},

{'count': u'740', 'year': u'1596'},

{'count': u'738', 'year': u'1612'},

{'count': u'718', 'year': u'1590'},

{'count': u'717', 'year': u'1610'},

{'count': u'715', 'year': u'1602'},

{'count': u'680', 'year': u'1606'},

{'count': u'674', 'year': u'1603'},

{'count': u'639', 'year': u'1603'},

{'count': u'637', 'year': u'1603'},

{'count': u'634', 'year': u'1590'},

{'count': u'633', 'year': u'1599'},

{'count': u'616', 'year': u'1596'},

{'count': u'614', 'year': u'1596'},

{'count': u'612', 'year': u'1595'},

{'count': u'607', 'year': u'1603'},

{'count': u'579', 'year': u'1593'},

{'count': u'570', 'year': u'1600'},

{'count': u'541', 'year': u'1599'},

{'count': u'525', 'year': u'1608'},

{'count': u'520', 'year': u'1599'},

{'count': u'518', 'year': u'1602'},

{'count': u'486', 'year': u'1595'},

{'count': u'470', 'year': u'1593'},

{'count': u'433', 'year': u'1609'},

{'count': u'429', 'year': u'1607'},

{'count': u'421', 'year': u'1611'},

{'count': u'399', 'year': u'1592'},

{'count': u'363', 'year': u'0'},

{'count': u'353', 'year': u'1594'},

{'count': u'287', 'year': u'1609'},

{'count': u'106', 'year': u'0'},

{'count': u'57', 'year': u'1609'}]

我相信它是您所需要的。比仅使用jsonjson.dumps对响应做一个就可以了。
