I think I understood Sigleton pattern, any suggestion?



from pyPgSQL import PgSQL

class Database(object):
    _sigletons = {}
    def __new__(cls):
        if cls not in cls._sigletons:
            cls._connection = PgSQL.connect(database='dbname',
                                            user='username',
                                            password='passwd',
                                            host='hostname')
            cls._sigletons[cls] = object.__new__(cls)
            pass
        return cls._sigletons[cls]
    
    def __init__(self):
        self.connection = Database._connection
        pass
    
    def cursor(self):
        return self.connection.cursor()
    
    #other methods follows here
