How can I make my loop command for a pythin discord bot work ?
17 octobre 2022, par Dioso I am kinda new to python and wanted to make a discord music bot. It works pretty well, except that I am not able to figure out how to code the queue loop command and the playing now command(this one gives me a full link instead of just the name). I have bolded the 2 commands that I cannot figure out.


from ast import alias
import discord
from discord.ext import commands

from youtube_dl import YoutubeDL

class music_cog(commands.Cog):

 self.bot = bot

 #remove the first element as you are currently playing it
 self.music_queue.pop(0)
