Python discord.py分割输出以绕过2000个字符限制的方法

Question

我试图通过discord将文本文件的内容输出到discord频道。我的问题是有2000个字符的限制。我已经能够通过使用下面的代码绕过这个问题

async def on_message(message):
    id = client.get_guild(73194604108722****)
    channels = ["football"]
    
    
    
    if str(message.channel) in channels:
        if message.content.find("!english") != -1:

            with open('/home/brendan/Desktop/englishfootball.txt', 'r') as file:
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())
                await message.channel.send(file.read(2000).strip())

运行此代码会导致一个400错误，说明无法发送空白消息，我认为这是由于存在额外的file.read（2000）语句，而不是文本文件中的内容（下面的错误消息）

  File "discordbot.py", line 62, in on_message
    await message.channel.send(file.read(2000).strip())
  File "/usr/lib/python3.8/site-packages/discord/abc.py", line 856, in send
    data = await state.http.send_message(channel.id, content, tts=tts, embed=embed, nonce=nonce)
  File "/usr/lib/python3.8/site-packages/discord/http.py", line 225, in request
    raise HTTPException(r, data)
discord.errors.HTTPException: 400 Bad Request (error code: 50006): Cannot send an empty message

一个积极的方面是所有数据都正确打印，但我只是想问，是否有人能想出一种更好的方法来执行此操作，从而导致400错误不显示

下面是上面正在读取的文本文件内容的示例

Thanks in advance to anyone who proposes a solution or provides advice.

Answer 1

有什么原因不能在发送之前，将读取和发送分开并检查读取结果是否为空

with open('/home/brendan/Desktop/englishfootball.txt', 'r') as file:
    msg = file.read(2000).strip()
    while len(msg) > 0:
        await message.channel.send(msg)
        msg = file.read(2000).strip()
