Try the "borg" pattern: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/66531 It's very simple and does what you need. Don't be put off by comments that "it's not a *real* singleton". Or, use a module-level object, e.g.: ----db.py---- class db_conn: def __init__(self, dbname, dbhost): self.conn = whatever(dbname, dbhost) conn = db_conn('mydb", "myhost") ----app.py---- import db ... cur = db.conn.cursor() cur.execute("select lkjlkj") Repeated imports of db by various modules in an application do *not* rerun the code in db.py . -- George -- http://mail.python.org/mailman/listinfo/python-list
