What you probably want here, based on your description is (untested):
@classmethod
def read_parameters(cls, path): # Note, the name is "cls". This is not
required, but is convention, similar to "self".
cls.dict_parameters = {1:"a",2:"b"}
@staticmethod creates a method that does not receive any special parameter,
so the signature would be "def read_parameters(path)".
Note that, personally, I would name the method "parse_parameters" to make
it clearer what it does.
