The anydbm module

This module provides a unified interface to the simple database drivers supported by Python.

When you open an existing database, the module uses whichdb to figure out what driver to use. When you create a new database, it checks for dbhash, gdbm, dbm, or dumbdbm, in that order.

# File: anydbm-example-1.py

import anydbm

db = anydbm.open("database", "c")
db["1"] = "one"
db["2"] = "two"
db["3"] = "three"
db.close()

db = anydbm.open("database", "r")
for key in db.keys():
    print repr(key), repr(db[key])

'2' 'two'
'3' 'three'
'1' 'one'
