- :mod:`whichdb` --- Guess which DBM module created a database
- ============================================================
- .. module:: whichdb
- :synopsis: Guess which DBM-style module created a given database.
- .. note::
- The :mod:`whichdb` module's only function has been put into the :mod:`dbm`
- module in Python 3.0. The :term:`2to3` tool will automatically adapt imports
- when converting your sources to 3.0.
- The single function in this module attempts to guess which of the several simple
- database modules available--\ :mod:`dbm`, :mod:`gdbm`, or :mod:`dbhash`\
- --should be used to open a given file.
- .. function:: 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'``.
