What happened to types.ClassType in python 3?

Question

I have a script where I do some magic stuff to dynamically load a module, and instantiate the first class found in the module. But I can't use types.ClassType anymore in Python 3. What is the correct way to do this now?

Answer 1

it was used for classic classes, in python3 they're gone.
I suppose you could use: issubclass(ClassName, object) for example or whatever your class derives from

Answer 2

I figured it out. It seems that classes are of type "type". Here is an example of how to distinguish between classes and other objects at runtime.

>>> class C: pass
... 
>>> type(C)
<class 'type'>
>>> isinstance(C, type)
True
>>> isinstance('string', type)
False
