This module provides an interface to the GNU DBM (GDBM) library.
This module is quite similar to the dbm module, but uses GDBM instead to
provide some additional functionality. Please note that the file formats
created by GDBM and dbm are incompatible.
GDBM objects behave like mappings (dictionaries), except that keys and
values are always strings. Printing a GDBM object doesn't print the
keys and values, and the items() and values() methods are not

- open(filename, [flag, [mode]]) -> dbm_object
- Open a dbm database and return a dbm object. The filename argument is
- the name of the database file.
- The optional flag argument can be 'r' (to open an existing database
- for reading only -- default), 'w' (to open an existing database for
- reading and writing), 'c' (which creates the database if it doesn't
- exist), or 'n' (which always creates a new empty database).
- Appending f to the flag opens the database in fast mode; altered
- data will not automatically be written to the disk after every
- change. This results in faster writes to the database, but may
- result in an inconsistent database if the program crashes while the
- database is still open. Use the sync() method to force any
- unwritten data to be written to the disk.
- 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.
