kv 0.4.1

KV在SQLite之上提供了一个类似于字典的接口。键可以是Unicode字符串、数字或None。值以JSON格式存储。

>>> from kv import KV
>>> db = KV('/tmp/demo.kv')
>>> db['hello'] = 'world'
>>> db[42] = ['answer', 2, {'ultimate': 'question'}]
>>> dict(db)
{42: [u'answer', 2, {u'ultimate': u'question'}], u'hello': u'world'}

有一个使用SQLite事务API的锁定功能

>>> with kv.lock():
...   l = db[42]
...   l += ['or is it?']
...   db[42] = l

就是这样。代码非常简单。代码
