如何同时运行两个python循环？

import threading

def loop1():
    for i in range(5):
        print("Loop 1:", i)

def loop2():
    for i in range(5):
        print("Loop 2:", i)

thread1 = threading.Thread(target=loop1)
thread2 = threading.Thread(target=loop2)

thread1.start()
thread2.start()

thread1.join()
thread2.join()

import multiprocessing

def loop1():
    for i in range(5):
        print("Loop 1:", i)

def loop2():
    for i in range(5):
        print("Loop 2:", i)

process1 = multiprocessing.Process(target=loop1)
process2 = multiprocessing.Process(target=loop2)

process1.start()
process2.start()

process1.join()
process2.join()
