Python itself has answers to your questions:
>>> isinstance(3, int)
True
>>> isinstance("3", int)
False
>>> isinstance(int, type)
True
>>> isinstance(type, int)
False
>>> isinstance(type, type)
True
>>> isinstance(3, type)
False
>>> isinstance(int, 3)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: isinstance() arg 2 must be a type or tuple of types
>>> isinstance(3, object)
True
>>> isinstance("3", object)
True
>>> isinstance(int, object)
True
>>> isinstance(type, object)
True
>>> isinstance(object, object)
True
