Unlike shelve, many processes can access the database simultaneously. Changing a value in database is immediately visible to other processes accessing the same database. Concurrency is possible because the values are stored in separate files. Hence the "database" is a directory where *all* files are governed by PickleShare. Example usage:: from pickleshare import * db = PickleShareDB('~/testpickleshare') db.clear() print "Should be empty:",db.items() db['hello'] = 15 db['aku ankka'] = [1,2,313] db['paths/are/ok/key'] = [1,(5,46)] print db.keys() del db['aku ankka'] This module is certainly not ZODB, but can be used for low-load (non-mission-critical) situations where tiny code size trumps the advanced features of a "real" object database.
