Python收发贺卡

以下是两种Python收发贺卡的例子：
1. 使用线程发送贺卡[^1]

import threading

def send_card(name):
    print("Sending card to", name)

def main():
    names = ["Alice", "Bob", "Charlie"]
    threads = []
    for name in names:
        t = threading.Thread(target=send_card, args=(name,))
        threads.append(t)
        t.start()
    
    for t in threads:
        t.join()

if __name__ == "__main__":
    main()

2. 使用进程发送贺卡

import multiprocessing

def send_card(name):
    print("Sending card to", name)

def main():
    names = ["Alice", "Bob", "Charlie"]
    processes = []
    for name in names:
        p = multiprocessing.Process(target=send_card, args=(name,))
        processes.append(p)
        p.start()
    
    for p in processes:
        p.join()

if __name__ == "__main__":
    main()
