我正在构建一个简单的聊天机器人，对于保险公司来说，它主要有3个步骤（在step_lists中），但是它也应该理解一些关键词池（如果用户说给我您的电话，那么聊天机器人会发送电话号码并返回到上一个“分支”，）。问题是，这仅适用于一个简单的答案问题，我想添加一个“分支”（由诸如紧急事件或询问付款方式之类的关键字触发的一组问题），其中包含两个以上的问题。
在要检查的代码中（processQuestions（）），如果用户输入意图触发“分支”列表问题，则PROX变量将为False并转到另一个分支，如果该分支问题不再存在问题（并且只有在分支没有选择结束对话的情况下），它将返回True并转到上一个分支（它可以是主列表或另一个分支）
我同时使用了模拟列表，然后我们将使用NLP处理器（例如对话框或watson）
