我是Python的新手，我正在与我的老师在Raspberry Pi 3上开发一个基本的语音辅助。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，有很多问题我无法回答。你能帮我一下吗?我想开发一个助手，可以在谷歌上搜索，在YouTube上播放音乐，并显示天气预报。AI.py是我的主文件，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文件来搜索我的请求。这与YouTube文件类似。
问题是Google_Search.py和YouTube_search.py只是继续运行，不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AI.py文件来停止或重新打开它们。这是密码，请帮我一下。非常感谢。
这是AI.py文件

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。如果您想调用导入文件中的程序，您应该使用函数并调用它。例如:
test.py
def myFunction():
print("Hello")
main.py
import test
test.myFunction()
