Python的基本语音辅助

Question

我是Python的新手，我正在Raspberry Pi 3上和我的老师一起开发一个基本的语音助手。这个项目中的代码是由我收集和修复的。然而，作为一个新手，有许多问题我无法回答。你能帮帮我吗？我想开发一个帮助，可以搜索谷歌，播放音乐在YouTube和显示天气预报。AI.py是我的主要文件，Google_Search.py用于搜索，YouTube_Search.py用于播放音乐。当我请求搜索时，AI.py将导入Google_Search.py文件以搜索我的请求。它与YouTube文件类似。

问题是Google_Search.py和YouTube_search.py只是继续运行，不要停止或允许我继续使用AI.py文件。我想运行这两个文件，而我仍然可以运行与AI.py文件，以停止或重新打开它们。这是密码，请帮帮我。非常感谢。

这是AI.py文件

while True:

这是Google_Search.py文件

，这是YouTube_Search.py

Python中的import关键字用于将其他Python源代码文件加载到当前解释器会话中。导入文件时，将首先运行该文件。如果要在导入的文件中调用程序，则应该使用函数并调用该函数。例如：

test.py

def myFunction():
  print("Hello")

main.py

import test
test.myFunction()
