问题描述
这是我从 google bigquery 解析的数据:
<代码>{u'kind': u'bigquery#queryResponse',你行':[{你'f':[{u'v': u'the'},{你'v':你'995'},{你'v':你'1600'}]},{你'f':[{u'v': u'the'},{你'v':你'942'},{你'v':你'1607'}]},{你'f':[{u'v': u'the'},{你'v':你'937'},{你'v':你'1599'}]},{你'f':[{u'v': u'the'},{你'v':你'894'},{你'v':你'1598'}]},{你'f':[{u'v': u'the'},{你'v':你'848'},{你'v':你'1592'}]},{你'f':[{u'v': u'the'},{你'v':你'841'},{你'v':你'1590'}]},{你'f':[{u'v': u'the'},{你'v':你'786'},{你'v':你'1603'}]},{你'f':[{u'v': u'the'},{你'v':你'779'},{你'v':你'1609'}]},{你'f':[{u'v': u'the'},{你'v':你'762'},{你'v':你'1597'}]},{你'f':[{u'v': u'the'},{你'v':你'753'},{你'v':你'1594'}]},{你'f':[{u'v': u'the'},{你'v':你'740'},{你'v':你'1596'}]},{你'f':[{u'v': u'the'},{你'v':你'738'},{你'v':你'1612'}]},{你'f':[{u'v': u'the'},{你'v':你'718'},{你'v':你'1590'}]},{你'f':[{u'v': u'the'},{你'v':你'717'},{你'v':你'1610'}]},{你'f':[{u'v': u'the'},{你'v':你'715'},{你'v':你'1602'}]},{你'f':[{u'v': u'the'},{你'v':你'680'},{你'v':你'1606'}]},{你'f':[{u'v': u'the'},{你'v':你'674'},{你'v':你'1603'}]},{你'f':[{u'v': u'the'},{你'v':你'639'},{你'v':你'1603'}]},{你'f':[{u'v': u'the'},{你'v':你'637'},{你'v':你'1603'}]},{你'f':[{u'v': u'the'},{你'v':你'634'},{你'v':你'1590'}]},{你'f':[{u'v': u'the'},{你'v':你'633'},{你'v':你'1599'}]},{你'f':[{u'v': u'the'},{你'v':你'616'},{你'v':你'1596'}]},{你'f':[{u'v': u'the'},{你'v':你'614'},{你'v':你'1596'}]},{你'f':[{u'v': u'the'},{你'v':你'612'},{你'v':你'1595'}]},{你'f':[{u'v': u'the'},{你'v':你'607'},{你'v':你'1603'}]},{你'f':[{u'v': u'the'},{你'v':你'579'},{你'v':你'1593'}]},{你'f':[{u'v': u'the'},{你'v':你'570'},{你'v':你'1600'}]},{你'f':[{u'v': u'the'},{你'v':你'541'},{你'v':你'1599'}]},{你'f':[{u'v': u'the'},{你'v':你'525'},{你'v':你'1608'}]},{你'f':[{u'v': u'the'},{你'v':你'520'},{你'v':你'1599'}]},{你'f':[{u'v': u'the'},{你'v':你'518'},{你'v':你'1602'}]},{你'f':[{u'v': u'the'},{你'v':你'486'},{你'v':你'1595'}]},{你'f':[{u'v': u'the'},{你'v':你'470'},{你'v':你'1593'}]},{你'f':[{u'v': u'the'},{你'v':你'433'},{你'v':你'1609'}]},{你'f':[{u'v': u'the'},{你'v':你'429'},{你'v':你'1607'}]},{你'f':[{u'v': u'the'},{你'v':你'421'},{你'v':你'1611'}]},{你'f':[{u'v': u'the'},{你'v':你'399'},{你'v':你'1592'}]},{你'f':[{u'v': u'the'},{你'v':你'363'},{你'v':你'0'}]},{你'f':[{u'v': u'the'},{你'v':你'353'},{你'v':你'1594'}]},{你'f':[{u'v': u'the'},{你'v':你'287'},{你'v':你'1609'}]},{你'f':[{u'v': u'the'},{你'v':你'106'},{你'v':你'0'}]},{你'f':[{u'v': u'the'},{你'v':你'57'},{你'v':你'1609'}]}],你的工作参考:{u'projectId': u'670640819051',u'jobId': u'job_5bf745fcee8b470e997d8ea90f380e68'},你'jobComplete':是的，u'totalRows': u'42',你的架构':{你的字段:[{u'type': u'STRING',u'name': u'word',u'mode': u'NULLABLE'},{u'type': u'INTEGER',u'name': u'word_count',u'mode': u'NULLABLE'},{u'type': u'INTEGER',u'name': u'corpus_date',u'mode': u'NULLABLE'}]}}作为 Python 新手，我真的不知道如何解析这些数据以创建如下 json 对象:
<预><代码>[{'count': 200, 'year': 2008},{'计数':240，'年':2010}，{'计数':290，'年份':2009}]谁能给我一些关于如何开始的提示?
示例
[{u'v': u'the'}, {u'v': u'995'}, {u'v': u'1600'}]在这个词中，'the'，count 是 995，year 是 1600.所以它如下.
解决方案
如果 'Z' 是你的大词典，那么在 'response' 你会得到你需要的结构.
导入json回应 = []对于 z['rows'] 中的行:对于 key，在 row.iteritems() 中的 dict_list:计数 = dict_list[1]年 = dict_list[2]response.append({'count': count['v'], 'year': year['v']})打印 json.dumps(响应)回复后你会得到以下信息:
[{'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.只使用 json 并执行 json.dumps到响应，就是这样.

Being a Python newbee, I really have no idea about how to go about parsing this data to create a json object like below:
[
{'count': 200, 'year': 2008},
{'count': 240, 'year': 2010},
{'count': 290, 'year': 2009}
]
Can any one give me any hint about how to get started?
Example
[{u'v': u'the'}, {u'v': u'995'}, {u'v': u'1600'}]
In this for the word 'the', count is 995 and year is 1600. And so it follows.
解决方案
If 'Z' is your big dictionary, on 'response' you will get the structure you need.
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)
On response you will get the following:
[{'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'}]
I believe its what you need.
Than only use json and do a json.dumps to the response and that's it.
