FWIW, this can run into unchecked infinite recursion easily: class C: # There's no @classmethod decorator here as there should have been def __instancecheck__(self, arg): return False isinstance(42, C) The reason is that on line 372 in classobject.c there's a call to PyObject_IsInstance(self, klass).
