【中文标题】如何更改工作的 python 程序，使其作为 python flask 程序运行

【英文标题】：How can I change a working python program so that it runs as python flask program

【问题描述】：

我有一个 python 程序，一个专家系统，它可以作为一个纯 python 程序运行。但我现在想将它作为 python 烧瓶程序运行，以便它可以显示在浏览器上，并且可能集成为 whatsapp 或 sms 聊天机器人。 我正在寻找从仅 python 到将代码变成某种聊天机器人的变化。

由于质量低下，我已将此标记为需要改进。您不能只提供一段代码并期望有人转换它。

【参考方案1】：

您需要按照 Flask 教程中的步骤进行操作。看看这个one
