이 예제를 python2에서 python3으로 변환하는 방법

Question

github의 예제를 python2에서 python3으로 변환하고 이해가 안되는 문제로 변환하려고합니다.

원래 내가 다음 패치를 적용하고 여기서 SampleApp 초기화 방법에 너무 많은 인수에 대한 오류 메시지가 https://gist.github.com/EugeneBakin/76c8f9bcec5b390e45df 입니다. 유일한 호출이 아무런 언급도하지 않았을 때 왜 원본이 그것의 args와 ** kwargs를 가지고 있었는지 나는 이해하지 못하기 때문에, 무언가는 나를 위해 합산하지 않는다. 그러나 그것은 python2에서 작동했기 때문에 python3에서도 사용하기를 바랬습니다. 사용법이 유용하다고 인식했기 때문입니다.

그러나 오류 메시지의 스택 추적에 해당 통화 또는 해당 통화에 대한 통화가 포함되어 있지 않기 때문에 문제가되지 않을 수 있습니다. 또 다른 퍼즐.

실제 사용 사례에 적용 할 때 필요할 수 있으므로 인수를 맹목적으로 제거하지 않고이 문제를 해결하고 싶습니다.

나는 또한 위험하다고 생각하고 독자에게 유용한 정보로 숨길 때 *로 가져 오기를 제거하려고합니다.
