Python 3 pygame 混音器 - 下一首歌

Question

我是python的新手，所以请保持友善。 我最近开始了一个项目，使用 pygame 和 tkinter 的 mp3 播放器遇到了问题。 当前一首歌曲播放完毕后，我无法让播放器转到下一首歌曲。 有什么办法可以做到这一点，或者有什么办法可以看出这首歌有多长？

其他一切都运行良好，播放良好。 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()

Answer 2

你可以试试这个。 这个对我有用。 现在我只想弄清楚如何让它跳到队列中的下一首歌曲。

from os import listdir
from pygame import mixer
from random import shuffle
from tkinter import Tk

window = Tk()
mixer.init()

# get list of files
music_files = listdir('./Music')

# Get number of files
file_range = len(music_files)

# Get first file and load then queue all remaining files
my_file = music_files.__getitem__(0)
mixer.music.load(f"./Music/{my_file}")
for song in range(1, file_range-1):
    mixer.music.queue(f"./Music/{music_files.__getitem__(song)}")

play_music = True
shuffle_music = True
# Shuffle if needed
if shuffle_music:
    shuffle(music_files)

# Creates and loops the queue each time the mixer stops playing music
while play_music:
    while not mixer.music.get_busy():
        # Get first file and load then queue all remaining files
        mixer.music.load(f"./Music/{music_files.__getitem__(0)}")
        for song in range(1, file_range - 1):
            mixer.music.queue(f"./Music/{music_files.__getitem__(song)}")
        mixer.music.play()

window.mainloop()
