如何在discord.py中跟踪列表

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.typing = False
intents.presences = False

bot = commands.Bot(command_prefix='!', intents=intents)

tracked_list = []

@bot.event
async def on_ready():
    print(f'Bot is ready. Logged in as {bot.user.name}')

@bot.command()
async def track(ctx, item: str):
    if item not in tracked_list:
        tracked_list.append(item)
        await ctx.send(f'Added {item} to the tracked list.')
    else:
        await ctx.send(f'{item} is already in the tracked list.')

@bot.command()
async def untrack(ctx, item: str):
    if item in tracked_list:
        tracked_list.remove(item)
        await ctx.send(f'Removed {item} from the tracked list.')
    else:
        await ctx.send(f'{item} is not in the tracked list.')

@bot.command()
async def listtracked(ctx):
    if len(tracked_list) > 0:
        await ctx.send('Items in the tracked list:')
        for item in tracked_list:
            await ctx.send(item)
    else:
        await ctx.send('The tracked list is empty.')

bot.run('YOUR_DISCORD_TOKEN')
