python - 如何在给定时间后插入用于随机化和操作的命令

Question

现在在我的代码中，我将它写出来以在 !join 命令之后播放音频文件。我想将它更改为每 40 分钟后的命令，并且我希望能够从列表中选择一个随机文件来播放。关于如何调整我的代码的帮助会很棒!
我的代码:

from discord.ext import commands
from discord import FFmpegPCMAudio
 
client = commands.Bot(command_prefix = '!')
@client.command(pass_context=True)
async def join(ctx):
    if (ctx.author.voice):
        channel = ctx.message.author.voice.channel
        voice = await channel.connect()
        source = FFmpegPCMAudio('AUDIO FILE')
        player = voice.play(source)
    else:
        await ctx.send("User not in a voice channel, unable to connect.")
 
@client.command(pass_context=True)
async def leave(ctx):
    if (ctx.voice_client):
        await ctx.guild.voice_client.disconnect()
        await ctx.send("I have left the voice channel.")
    else:
         await ctx.send("I am not in a voice channel.")
 
 
 
client.run('BOT TOKEN')```

首先，在代码顶部添加:

from discord.ext import tasks 
import random 

然后，在代码中的任意位置添加:

@tasks.loop(minutes=40)
async def play_random_song():
    for channel in voicechannels: #voicechannels is your list of voicechannels where a random song should be played every 40 minutes
        song = random.choice(list_of_songs) #list_of_songs is your list of all the songs audio files you want to be able to be randomly played
        voice = await channel.connect()
        source = FFmpegPCMAudio(song)
        player = voice.play(source)

然后启动您在 on_ready 中创建的任务:

@client.event
async def on_ready():
    play_random_song.start()

这意味着您的最终代码是:

from discord.ext import commands
from discord import FFmpegPCMAudio
from discord.ext import tasks 
import random 
 
client = commands.Bot(command_prefix = '!')
@client.command(pass_context=True)
async def join(ctx):
    if (ctx.author.voice):
        channel = ctx.message.author.voice.channel
        voice = await channel.connect()
        source = FFmpegPCMAudio('AUDIO FILE')
        player = voice.play(source)
    else:
        await ctx.send("User not in a voice channel, unable to connect.")
 
@client.command(pass_context=True)
async def leave(ctx):
    if (ctx.voice_client):
        await ctx.guild.voice_client.disconnect()
        await ctx.send("I have left the voice channel.")
    else:
         await ctx.send("I am not in a voice channel.")
 
 
@tasks.loop(minutes=40)
async def play_random_song():
    for channel in voicechannels: #voicechannels is your list of voicechannels where a random song should be played every 40 minutes
        song = random.choice(list_of_songs) #list_of_songs is your list of all the songs audio files you want to be able to be randomly played
        voice = await channel.connect()
        source = FFmpegPCMAudio(song)
        player = voice.play(source) 

@client.event
async def on_ready():
    play_random_song.start()

client.run('BOT TOKEN')
