Example: how to make a queue command for lavalink discord py

##This was in a cog
from discord.ext import commands
import lavalink
from discord import utils
from discord import Embed
import re
import math
import discord

url_rx = re.compile(r'https?://(?:www\.)?.+')

class MusicCog(commands.Cog):
  def __init__(self, bot):
    self.bot = bot
    self.bot.music = lavalink.Client(self.bot.user.id)
    self.bot.music.add_node('localhost', 6666, 'Humpday!', 'na', 'music-node')
    self.bot.add_listener(self.bot.music.voice_update_handler, 'on_socket_response')
    self.bot.music.add_event_hook(self.track_hook)

    async def cog_before_invoke(self, ctx):
        guild_check = ctx.guild is not None
 
##below is ths maine queue command
 @commands.command(name='queue')
  async def queue(self, ctx, page: int = 1):
    player = self.bot.music.player_manager.get(ctx.guild.id)

    items_per_page = 10
    pages = math.ceil(len(player.queue) / items_per_page)

    start = (page - 1) * items_per_page
    end = start + items_per_page

    queue_list = ''
    for index, track in enumerate(player.queue[start:end], start=start):
      queue_list += f'`{index + 1}.` [**{track.title}**]({track.uri})\n'

    embed = discord.Embed(colour=discord.Color.blurple(),
                          description=f'**{len(player.queue)} tracks**\n\n{queue_list}')
    embed.set_footer(text=f'Viewing page {page}/{pages}')
    await ctx.send(embed=embed)

##below this just finishes up the cog
def setup(bot):
  bot.add_cog(MusicCog(bot))
##feel free to uses this
