print type(v[0])

str_to_load = json.dumps(v[0])

json_data =  json.loads(str_to_load)
print json_data
for row in json_data.get('rows',[]):
    print row

Answer 1

这不是有效的JSON;并非所有JavaScript都是JSON。您可以尝试使用以下命令将其转换为JSON：

import re

def repair_json(val):
    return re.sub(r'(\w+):', r'"\1":', 
                  val.replace('"', '\u0022').replace("'", '"'))

此：

• 引用带有JSON \uxxxx unicode转义序列的嵌入式双引号。
• 用双引号替换单引号;如果任何JSON字符串值包含单引号，这将无效。
• 引用关键名称;再次，如果值中有任何带冒号的嵌入单词，这些也会被引用并被破坏。

对于您的给定值，此方法有效：

>>> json.loads(repair_json(v[0]))

rows列表是store键下的一个键：

for row in data['store']['rows']:
    print row

为了探索这些结构，我发现pprint.pprint() function非常宝贵。
