Python 操作BDB (1)

micromax

　　Python 对BDB的访问支持的非常好，在内建的lib里就有对BDB的访问支持,
　　见博文 http://gashero.yeax.com/?p=5#id14
　　我简单写了个K-v的例子，记录如下：

import bsddb  
class BDBTest(object):
def __init__(self):
self.db = bsddb.btopen('test.db', 'c')
print "Opened"
self.db["2009-08-14 22:00"] = "gg"
self.db["2009-08-15 22:00"] = "cc"
self.db["2009-07-15 00:00"] = "tt"
self.db["2009-08-16 22:00"] = "gg"
self.db["2009-08-16 23:00"] = "gx"
# K-V
print self.db["2009-08-14 22:00"]
# Use Previous and next allocate the cursor
self.db.set_location('2009-08-15')
#
print self.db.next()
print self.db.previous()
#d = bsddb.hashopen("aaa.db", "c")
if __name__ == '__main__':
try:
bdb = BDBTest()
except:
print "Exception Happen"

 　　在接下来的系列里，还会对BDB的的访问方式进行进一步的探究。
