如何制作不和谐机器人循环音频？ [不和谐.py]

我想让机器人播放一段音频，当音频结束时，它将重播该音频。

我拥有的：

@client.command()
async def play(ctx):
await ctx.channel.purge(limit=1)
channel = ctx.author.voice.channel
if channel:
    print(channel.id)
    await channel.connect()
guild = ctx.guild
audio_source = discord.FFmpegPCMAudio('audio.mp3')
voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=guild)
if not voice_client.is_playing():
    voice_client.play(audio_source, after=None)

discord.VoiceClient.Play() has an after音频流结束时调用的参数。通常，它应该用于显示错误消息，但您可以使用它来重复歌曲，如下所示：

@client.command()
async def play(ctx):
    await ctx.channel.purge(limit=1)
    channel = ctx.author.voice.channel
    voice = get(self.bot.voice_clients, guild=ctx.guild)

    def repeat(guild, voice, audio):
        voice.play(audio, after=lambda e: repeat(guild, voice, audio))
        voice.is_playing()

    if channel and not voice.is_playing():
        audio = discord.FFmpegPCMAudio('audio.mp3')
        voice.play(audio, after=lambda e: repeat(ctx.guild, voice, audio))
        voice.is_playing()
