중첩 인수가 컴파일되지 않음

Question

코드를 Python 3 모듈로 컴파일하려고합니다. 내가 IDLE에서 "실행 모듈"을 선택,하지만 난 분포를 만들려고 할 때 다음과 같은 구문 오류를받을 때 잘 실행 :

File "/usr/local/lib/python3.2/dist-packages/simpletriple.py", line 9 
    def add(self, (sub, pred, obj)): 
       ^
SyntaxError: invalid syntax 

사람이 구문에 어떤 문제가 있는지 지적 도와 드릴까요? 여기에 전체 코드는 다음과 같습니다

PEP 3113는 "튜플 매개 변수를 풀고"이 기능은, 파이썬 3에서 제거 된 이유는 어떻게 포트를 사용하는 코드를에 설명을 설명합니다. 페이스트 빈에

def add(self, sub_pred_obj): 
    sub, pred, obj = sub_pred_obj 
    self._addToIndex(self._spo, sub, pred, obj) 
    self._addToIndex(self._pos, pred, obj, sub) 
    self._addToIndex(self._osp, obj, sub, pred)
