Have a look at __spec__, specifically __spec__.origin: >>> import sys >>> _fi = sys.modules['_frozen_importlib'] >>> _fi <module '_frozen_importlib' (frozen)> >>> _fi.__spec__ ModuleSpec(name='_frozen_importlib', loader=<class '_frozen_importlib.FrozenImporter'>, origin='<frozen>') >>> _fi.__spec__.origin '<frozen>' I've not looked up in the importlib docs to confirm, but that should mean that frozen modules should have a __spec__.origin that contains "frozen".
