我怎么能经常检查 Python 3.8 中的值

Question

So I'm programming a discord bot (using discord.py library) that should manage RPG characters and some other things, I want to manage leveling/xp with the bot. My question is : is there a way that the bot will check every x seconds all the players xp amount ? I know I could write something like if character.xp == xp_amount in every parts that grant xp/create a function that does it and call in these parts, but it is possible to do it "passively" ?

You can use Python standard multiprocessing or threading module to check the value each x second.

Here's a code example for using threading module

import time
import threading


VALUE = 10

def check_value(second: int) -> None:
    """Check global variable `VALUE` periodically

    Args:
        second (int): the checking interval
    """

    while True:
        if VALUE == 10:
            print('Value is 10')
        time.sleep(second)

if __name__ == "__main__":

    thread = threading.Thread(target=check_value, args=(2,))
    thread.start()
    # do other stuff here
