Question

我正在制作一个音乐机器人，并且在某些方面很挣扎。我不知道当当前曲目结束后如何制作跳过部分或播放队列中的下一首歌曲。有什么帮助吗？这是所有代码（所有这些都是为了以防万一）

队列部分位于底部附近，跳过部分也位于底部附近，并且正在此处播放歌曲。

import os
import re
import urllib.request

from discord.ext import commands
from discord.utils import get

bot = commands.Bot(command_prefix='g.')
token = '<mytoken>'

@bot.command(pass_context=True)
async def play(ctx, *args: str):
    search = '+'.join(args)
    print(search)
    if search == " ":
        await ctx.send("Uso: g.play (Video)")
        return
    else:
        html = urllib.request.urlopen("https://www.youtube.com/results?search_query=" + search)
        video_ids = re.findall(r"watch\?v=(\S{11})", html.read().decode())
        url = "https://www.youtube.com/watch?v=" + video_ids[0]
        print(url)

        def check_queue():

            if Queue_infile is True:
                DIR = os.path.abspath(os.path.realpath("Queue"))
                length = len(os.listdir(DIR))
                still_q = length - 1
