如何在python中使用对象作为多进程的值

import multiprocessing
from multiprocessing import Manager

manager = Manager()

shared_list = manager.list()

def worker(shared_list):
    shared_list.append("Hello from process {}".format(multiprocessing.current_process().name))

processes = []
for i in range(5):
    p = multiprocessing.Process(target=worker, args=(shared_list,))
    processes.append(p)
    p.start()

for p in processes:
    p.join()

print(shared_list)

import multiprocessing
from multiprocessing import Manager

def worker(shared_list):
    shared_list.append("Hello from process {}".format(multiprocessing.current_process().name))

if __name__ == '__main__':
    manager = Manager()
    shared_list = manager.list()

    processes = []
    for i in range(5):
        p = multiprocessing.Process(target=worker, args=(shared_list,))
        processes.append(p)
        p.start()

    for p in processes:
        p.join()

    print(shared_list)
