This document is for an old version of Python that is no longer supported. You should upgrade and read the Python documentation for the current stable release.

11.7. `whichdb` — Guess which DBM module created a database¶

Note

The whichdb module’s only function has been put into the dbm module in Python 3. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.

The single function in this module attempts to guess which of the several simple database modules available—dbm, gdbm, or dbhash—should be used to open a given file.

whichdb.whichdb(filename)¶: Returns one of the following values: None if the file can’t be opened because it’s unreadable or doesn’t exist; the empty string ('') if the file’s format can’t be guessed; or a string containing the required module name, such as 'dbm' or 'gdbm'.
