It's exactly like a class. It's an immutable class. You are making
assumptions about what classes must be able to do.

In fact, object acts just like a user-defined class, with __slots__
set to empty:
>>> class MyObj(object):
... __slots__ = ()
...
>>> o = MyObj()
>>> o.x = 3
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'MyObj' object has no attribute 'x'
See
It's called a super class but it doesn't quite work like a normal class.
>>> OBJ = object()
>>> OBJ.x = 3
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'object' object has no attribute 'x'
I can fix this by creating a NULL class.
>>> class NullObject(object): pass
