如何在python中拥有2个“区域”

import threading

def task1():
    # 执行任务1的代码

def task2():
    # 执行任务2的代码

if __name__ == "__main__":
    thread1 = threading.Thread(target=task1)
    thread2 = threading.Thread(target=task2)
    thread1.start()
    thread2.start()
    thread1.join()
    thread2.join()

import multiprocessing

def task1():
    # 执行任务1的代码

def task2():
    # 执行任务2的代码

if __name__ == "__main__":
    process1 = multiprocessing.Process(target=task1)
    process2 = multiprocessing.Process(target=task2)
    process1.start()
    process2.start()
    process1.join()
    process2.join()
