7.8 dumbdbm -- Portable implementation of the simple DBM interface.

A simple and slow database implemented entirely in Python. This should only be used when no other DBM-style database is available.

open (filename[, flag[, mode]])
Open the database file filename and return a corresponding object. The optional flag argument can be 'r' to open an existing database for reading only, 'w' to open an existing database for reading and writing, 'c' to create the database if it doesn't exist, or 'n', which will always create a new empty database. If not specified, the default value is 'r'.

The optional mode argument is the Unix mode of the file, used only when the database has to be created. It defaults to octal 0666 (and will be modified by the prevailing umask).

error
Raised for errors not reported as KeyError errors.
