And much sense is made. If there is a generic instance test that I have
missed I'd be willing to work around this minor flaw. That the definition is
an instance of 'object' is a case that should be handled by the function
though.

Everything in python is an instance of something. Objects all the way down...
isinstance(object, object)
True
So, there is no function you are overlooking because there is nothing that is
not an instance.

It only fails when checking for 'object'. To think classes are instances is
absurd. Its like saying the chicken is the egg. I can understand that
classes are an instance of object in the interpreter, but, that isn't the
case in the interpreted. Thus

You are correct, B is not an instance of A. But both B and A are instances of
'type':
class A:
... pass
...
class B(A):
...pass
...
isinstance(A, type)
True
isinstance(B, type)
True
And type is a subclass of object.

Beautiful, thank you. This should be in the isinstance documentation for

#Example:

outputs: [True, True]
expected: [False, True]
As class a is not instantiated it should return false. As-is isinstance is just
a synonym for

I don't see why this is incorrect, type(a) - type, and object is a superclass
of type.
