您好，我在让我的 flask 和 html 输出正确的数据时遇到问题。我正在使用 Sumy 摘要库。基本上我试图总结 url 网页并将文本输出到 html 文档上。一切都运行良好，特别是对于我的 LSA 总结。问题是除了lsa之外它只输出第一句话。这就是为什么我创建了 para = ""变量来附加字符串以创建完整的段落。这有效，但仅适用于 LSA。我想知道是否有人询问我如何让其他摘要方法输出超过 1 个句子。所有这些算法在 IDLE 中都可以正常工作，只是不是我的 Flask 应用程序。抱歉英语不好。

原来鲍勃不是我叔叔。我的 return 语句位于 for 循环内部而不是外部。这个问题已经解决了。
