refactor: change methods not using its bound instance to staticmethods

The method doesn't use its bound instance. Decorate this method with `@staticmethod` decorator, so that Python does not have to instantiate a bound method for every instance of this class thereby saving memory and computation. Read more about staticmethods [here](https://docs.python.org/3/library/functions.html#staticmethod).
