I was confused by the comment below because it looks to me like `super()` would resolve the the parent class which is `object`. https://github.com/gregmalcolm/python_koans/blob/800cdf5db9e8539681723ca541e03b28e2117b28/koans/about_attribute_access.py#L106-L108 I substituted the line with `return super().__getattribute__(attr_name)` and it worked fine.
