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 0 0 1 1 2 4 3 9 4 16 5 25 6 36 7 49 8 64 9 81 >>> '8' in db True >>> db.sync() 0
