whichdb

Synopsis

whichdb(filename)

Opens the file specified by filename and determines which DBM-like package created the file. whichdb returns None if the file does not exist or cannot be opened and read. whichdb returns '' if the file exists and can be opened and read, but it cannot be determined which DBM-like package created the file (i.e., the file is not a DBM file). whichdb returns a string naming a module, such as 'dbm', 'dumbdbm', or 'dbhash', if it can determine which module can read the DBM-like file named by filename.
