Set static attributes...maybe.

[Beppe]

hi to everybody, 
in the following scrip I try to call the function read_parameters () but returns me that wants two arguments!?!?!
My intent is to have in the class, Engine (), some static attributes that can be used by  other instances without to redefine this every time.
These matters could be for example a path or a connection to a database.
suggestions?

regards
beppe

class Master(object):
    def __init__(self,):
        pass

class Engine(Master):
    dict_parameters = {}
    def __init__(self,):
        super(Engine, self).__init__()

    @staticmethod
    def read_parameters(self,path):
       
        self.dict_parameters = {1:"a",2:"b"}

    def check_parameters(self):
        self.read_parameters("hello_world")
               

foo=Engine()
foo.check_parameters()

p.s.
I'm on Debian 6
