在python中暫停thread

如果按了某個鍵，我想暫停并繼續threads。我試過了：如果按q，它會刪除"time.sleep(99999)（改為0），但是沒用，有人能幫我嗎？

import keyboard
from threading import Thread
from time import sleep

Thread1 = True
Thread2 = True

class main():
    def test1():
        if keyboard.is_pressed("q"):      #if keyboard is pressed q it will reomve the sleep
            time = 0
        time = 99999

        while Thread1 == True:
            print("Thread1")
            sleep(time)
    def test2():
        while Thread2 == True:
            print("Thread2")
            sleep(1)
        
    Thread(target=test1).start()
    Thread(target=test2).start()
    
main()
