Question

我是python的新手所以请你好。我最近开始了一个项目，带有pygame和tkinter的mp3播放器遇到了问题。当前的歌曲结束时，我无法让播放器转到下一首歌。有没有办法做到这一点，或以任何方式看这首歌有多长？

其他一切都很好，效果很好。这是代码：

#IMPORTS
from tkinter import *
from pygame import mixer
import pygame
import time


#listing music:
music = [
    "Tobu - Candyland.mp3",
    "Alan Walker - Spectre.mp3",
    "Tobu - Hope.mp3",
    "Tobu - Life.mp3",
    "Tobu - Mesmerize.mp3",
    "DEAF KEV - Invincible.mp3",
    "Different Heaven & EH!DE - My Heart.mp3",
    "Disfigure - Blank.mp3",
    "Ahrix - Nova.mp3",
    "Alan Walker - Fade.mp3",
    "jim-yosef-firefly-ncs-release.mp3",
    "Alan Walker - Force.mp3",

    ]

Answer 1

当您告诉Python歌曲结束后该怎么做时，您需要将其设置为如下事件：

def nextsong(event):
    global index
    index += 1
    pygame.mixer.music.load(listofsongs[index])
    pygame.mixer.music.play()
