python列表如何传递到线程？

import time

from threading import Thread

def work1(nums):

    nums.append(44)

    print("----in work1---",nums)

def work2(nums):

    #延时一会，保证t1线程中的事情做完

    time.sleep(1)

    print("----in work2---",nums)

g_nums = [11,22,33]

t1 = Thread(target=work1, args=(g_nums,))

t1.start()

t2 = Thread(target=work2, args=(g_nums,))

t2.start()
