Discord.py - Music bot queue command - discord.py

Question

I’m trying to code a simple music bot for discord in python. I tried coding a queue command so that I can queue a certain song (searching for songs and playing them etc. all work). This is my code for the queue command:
#commands.command()
async def checkqueue(self, ctx):
if len(self.song_queue[ctx.guild.id]) == 0:
return await ctx.send("Queue is empty")
else:
embed = discord.Embed(title="Song Queue", description="", colour=discord.colour.dark_gold())
i = 1
for url in self.song_queue[ctx.guild.id]:
embed.description += f"{i}) {url}\n"
i += 1
await ctx.send(embed=embed)
When the queue is empty, the bot sends a message in discord saying "Queue is empty”. When I use the play command, it adds a song to the queue. However, when I try to use the checkqueue command when there’s at least one song in the queue, the bot doesn’t send the embed. Not sure if this is a problem with the code in the queue command or outside the queue command, so here’s the cut-down version of the rest of my code in my commands Cog.
import discord

Answer 1

The issue that I was having with your code was the color of the Embed. Everything else went smoothly when I ran your code. When you referenced the Colour, you didn't properly access the function.
What you did:
embed = discord.Embed(title="Song Queue",
description="",
colour=discord.colour.dark_gold())
What you should do:
embed = discord.Embed(title="Song Queue",
description="",
colour=discord.Colour.dark_gold())
