Python - threading -如何创建一个播放列表函数，以便在后台使用线程运行？

import threading
import time

def play_song(song):
    print("正在播放歌曲：", song)
    time.sleep(2)  # 模拟播放歌曲需要的时间

def create_playlist(songs):
    threads = []
    for song in songs:
        thread = threading.Thread(target=play_song, args=(song,))
        thread.start()
        threads.append(thread)

    # 等待所有线程完成
    for thread in threads:
        thread.join()

if __name__ == "__main__":
    songs = ["歌曲1", "歌曲2", "歌曲3", "歌曲4", "歌曲5"]
    create_playlist(songs)
