如何在运行一个python文件的同时运行python文件

import threading

def run_file1():
    # 运行第一个Python文件的代码

def run_file2():
    # 运行第二个Python文件的代码

if __name__ == "__main__":
    thread1 = threading.Thread(target=run_file1)
    thread2 = threading.Thread(target=run_file2)
    
    thread1.start()
    thread2.start()
    
    thread1.join()
    thread2.join()

import multiprocessing

def run_file1():
    # 运行第一个Python文件的代码

def run_file2():
    # 运行第二个Python文件的代码

if __name__ == "__main__":
    process1 = multiprocessing.Process(target=run_file1)
    process2 = multiprocessing.Process(target=run_file2)
    
    process1.start()
    process2.start()
    
    process1.join()
    process2.join()
