The dumbdbm module
This is a very simple database implementation, similar to dbm and friends, but written in pure Python. It uses two files; a binary file (.dat) which contains the data, and a text file (.dir) which contain data descriptors.
The anydbm module uses this as the last choice.
# File: dumbdbm-example-1.py import dumbdbm db = dumbdbm.open("dumbdbm", "c") db["first"] = "fear" db["second"] = "surprise" db["third"] = "ruthless efficiency" db["fourth"] = "an almost fanatical devotion to the Pope" db["fifth"] = "nice red uniforms" db.close() db = dumbdbm.open("dumbdbm", "r") for key in db.keys(): print repr(key), repr(db[key])
$ python dumbdbm-example-1.py 'first' 'fear' 'third' 'ruthless efficiency' 'fifth' 'nice red uniforms' 'second' 'surprise' 'fourth' 'an almost fanatical devotion to the Pope'
