DATABASES in Python with dbm module

Python supports any DBM (database manager) and a similar interface. The main difference lies in the underrlying format. The database is a persistent dictionaries that work like normal Python dictionaries except that the data is written to and read from disk.

Amongst the different DBM, the anydbm module offers an alternative to choose the best DBM module available. If you need a very specific feature of another DBM module, use the anydbm module.

Quickstart with DBM

Let us first create a database:

>>> import anydbm
>>> # open a DB. The c option opens in read/write mode and creates the file if needed.
>>> db ='websites', 'c')
>>> # add an item
>>> db["item1"] = "First example"
>>> print db['item1']
"First example"
>>> # close and save
>>> db.close()


the key and value of each entry must be a string
