python object attributes and methods

Question

In python all data is object and any object should have attributes and methods. Does somebody know python object without any attributes and methods?

>>> len(dir(1))
64

Answer 1

This is easy to accomplish by overriding __dir__ and __getattribute__:

class Empty(object):
    def __dir__(self):
        return []
    def __getattribute__(self, name):
        raise AttributeError("'{0}' object has no attribute '{1}'".format(type(self).__name__, name))

e = Empty()
dir(e)
[]
e.__name__
AttributeError: 'Empty' object has no attribute '__name__'

(In python2, Empty needs to be a new-style class, so the class Empty(object): is required; in python3 old-style classes are extinct so class Empty: is sufficient.)
