Import class dynamically

[voltron]

Using inspect.getmodule(obj) and inspect.getsourcefile(obj) does not worked for me, but I managed to solve this by checking class name like this

if inspect.isclass(obj) and issubclass(obj, (FirstBaseClass, SecondBaseClass)) and obj.__name__ not in ("FirstBaseClass", "SecondBaseClass"):
    # do something

Thanks a lot for your help!
