artificial intelligence - Basic Voice Assistance with Python

Question

I am a newbie in Python and I am developing a basic Voice Assistance with my teachers on Raspberry Pi 3. The code in this project is collected and fixed by me. However, as a newbie there are many questions I cant answer. Can you help me, please? I want to develop an assistance which can search on Google, Play music on YouTube and show out the weather forecast. The AI.py is my main file, Google_Search.py is used for searching and YouTube_Search.py is used for playing music. When I ask for searching the AI.py will import the Google_Search.py file to search for my requests. It is similar with YouTube file.

The problem is the Google_Search.py and YouTube_search.py just keep running and don't stop or allow me to keep working with the AI.py file. I want to run these two files while I still can run with the AI.py file to stop or re-open them again. These are the code, Please help me out. Thanks so much.

This is AI.py file

import speech_recognition

x = response.json() 

while True:

        robot_brain = "I'm learning"

    print("Robot: " + robot_brain)
    robot_mouth.say(robot_brain)
    robot_mouth.runAndWait()

This is the Google_Search.py file

    robot_brain = ("Here is what I found for") + (" ") + str(you)
        
print("Robot: " + robot_brain)

os.system("pkill Google_Search")

This is the YouTube_Search.py

Answer 1

The import keyword in Python is used to load other Python source code files in to the current interpreter session. When you import a file, that file will be run first. If you want to call the program in your imported file, you should use a function and call that. For example:

test.py

def myFunction():
  print("Hello")

main.py

import test
test.myFunction()
