python berkeley 操作

先到http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/downloads/index-082944.html 下载6.1版本的，6.2版本py目前的库不支持

安装见：http://docs.oracle.com/cd/E17076_05/html/installation/build_unix.html

解压后

../dist/configure
make

make install

python安装：
https://pypi.python.org/pypi/bsddb3/6.1.1#downloads
python setup.py install
然后操作：

from bsddb3 import db 如果直接导入会出错的话

>>> import bsddb
>>> db = bsddb.btopen('spam.db', 'c')
>>> for i in range(10): db['%d'%i] = '%d'% (i*i)
...
>>> db['3']
'9'
>>> db.keys()
['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
>>> db.first()
('0', '0')
>>> db.next()
('1', '1')
>>> db.last()
('9', '81')
>>> db.set_location('2')
('2', '4')
>>> db.previous()
('1', '1')
>>> for k, v in db.iteritems():
...     print k, v
