Well object is an instance of object as well as of type:
>>> isinstance(object, object)
True
>>> isinstance(object, type)
True
>>> isinstance(type, object)
True
>>> isinstance(type, type)
True
>>> issubclass(object, type)
False
>>> issubclass(type, object)
True
>>> type.mro(type)
[<class 'type'>, <class 'object'>]
>>> type.mro(object)
[<class 'object'>]
>>> type(object)
<class 'type'>
>>> type(type)
<class 'type'>
