比较列表的索引

Question

所以我想说我有一个清单

@Override
    public void write(List<? extends IndexerInputVO> inputItems) throws Exception {


        int docsPerThread = Constants.NUMBER_OF_DOCS_PER_INDEX_WRITER_THREADS;
        int docSize = inputItems.size();
        int remainder = docSize%docsPerThread;
        int poolSize = docSize/docsPerThread;

        ExecutorService executor = Executors.newFixedThreadPool(poolSize+1);


        int fromIndex=0;
        int toIndex = docsPerThread;

        if(docSize < docsPerThread){
            executor.submit(new IndexWriterRunnable(this.luceneObjects,service,inputItems));
        }else{
            for(int i=1;i<=poolSize;i++){
                executor.submit(new IndexWriterRunnable(this.luceneObjects,service,inputItems.subList(fromIndex, toIndex)));
                fromIndex+=docsPerThread;
                toIndex+=docsPerThread;
            }

            if(remainder != 0){
                toIndex=docSize;
                executor.submit(new IndexWriterRunnable(this.luceneObjects,service,inputItems.subList(fromIndex, toIndex)));
            }
        }

        executor.shutdown();

        while(executor.isTerminated()){
            ;
        }

我想做的是这样的事情

answer_list = aaAbaBabBaBBaAbBAb

所以我试图检查每7个字符，如果字符是小写或大写B，我增加dimension_1_index = 0 dimension_1_b_answers = 0 while dimension_1_index <= len(answer_list): if answer_list[dimension_1_index] == "b" or "B": dimension_1_b_answers += 1 dimension_1_index += 7 else: continue print(dimension_1_b_answers) 。但是当我运行程序时，我没有得到任何结果。
