Python discord.py（重写）如何将命令使用能力缩小到单个通道？

我试图使这段代码只在特定的通道中工作。当我尝试在正确的通道中执行命令时，它只会发送大量错误。如果你想测试，我会添加我的导入。上次我试着问这个问题时，它被拒绝了。我仍然不知道该做什么，只是需要一点帮助，因为我对编写discord机器人还不熟悉

import discord
from discord.ext import commands, tasks
import os
import random
import asyncio
from asyncio import gather    
        
client = commands.Bot(command_prefix='.')
        
@client.command()
    async def car(ctx):
            pictures = [
            'https://car-images.bauersecure.com/pagefiles/78294/la_auto_show_11.jpg',

            channel = discord.utils.get()
            if channel == 705161333972140072:
                await ctx.channel.purge(limit=1)
                await ctx.send(f'{random.choice(pictures)}')
    
client.run('token')

您需要对命令功能进行一些更改：

固定压痕

使用

ctx.channel.id

而不是

channel

和

discord.utils.get（）

删除命令msg

你也可以使用

@client.command()
async def car(ctx):
    pictures = [
    'https://car-images.bauersecure.com/pagefiles/78294/la_auto_show_11.jpg',

    if ctx.channel.id == 705161333972140072:
        await ctx.message.delete()
        await ctx.send(random.choice(pictures))

client.run('token')
