Pythondiscord.py的方法来分割输出以绕过2000个字符的限制

Question

我正试图通过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一点

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文件。读取(2000(语句比文本文件中有内容(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，所有的数据都打印正确，但我只是想问，是否有人能想出一个更好的方法来做到这一点，从而导致400错误不显示？

以下是上正在读取的文本文件的内容示例

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

在发送之前，您是否不能单独进行读取和发送，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()
