tkinter 列表框混音器一次播放一首歌曲

Question

我不知道如何在不使用类的情况下让 tkinter 列表框在我的音乐播放器中播放连续的音频文件，我还不完全理解，因为我是 python 的新手。 我已经通过以下示例创建了一个事件，它在列表框中打印播放的歌曲和下一首歌曲，但我不知道如何从那里移动。

SONG_END = pygame.USEREVENT+1
pygame.mixer.music.set_endevent(SONG_END)

def check_event():
    for event in pygame.event.get():
        if event.type == SONG_END:
            print('music end event')
            for i in listbox.curselection():
                nxt_song = listbox.get(i + 1)
                print(nxt_song)

    root.after(100, check_event)

def next_s ():
# i cant figure out how to proceed from here to
# get the nxt song and play it
    pass

def play():
# activates the play button
    current = listbox.get(ACTIVE)
    playing_song['text'] = current # goes to a label displaying the current track name
    mixer.music.load(current)
    mixer.music.play()

# everything works as i want exept continuous play
# note that i dont want the player to have previous and next buttons   
    

Answer 1

这和播放歌曲是一样的。你必须做

pygame.mixer.load(next_song)

pygame.mixer.play()

您还必须调整当前歌曲的值，以便它在列表中移动。

current = next_song
