Open a persistent sqlite3-backed dictionary. The filename specificed is the path to the underlying database.
The flag and mode parameters have the same semantics as sqlite3dbm.dbm.open() (and, in fact, are directly passed through to this function).
The protocl and writeback parameters behave as outlined in shelve.open().
Exposes select() and get_many() which are available in sqlite3dbm.dbm but none of the other database modules. The dict object passed to the constructor must support these methods, which is generally done by calling sqlite3dbm.dbm.open().
The optional protocol and writeback parameters behave the same as they do for shelve.Shelf.
>>> import sqlite3dbm >>> db = sqlite3dbm.sshelve.open('mydb.sqlite3') >>> db['foo'] = 'bar' >>> db['baz'] = [1, 2, 3] >>> db['baz'] [1, 2, 3] >>> db.select('foo', 'baz') ['bar', [1, 2, 3]] >>> db.get_many('foo', 'qux', default='') ['bar', '']
