我有一个 discord.py 机器人来访问 Politics & 的 API战争，我有一个线程每 20 分钟检查一次以检查新活动.我已经尝试将这部分放在 on_ready 中，但这似乎会停止执行任何命令，所以我不得不创建一个线程.但是，当我尝试运行此代码并且有新活动要发送消息时，它会引发 RuntimeError:
I have a discord.py bot to access the API for Politics & War, and I have a thread to check every 20 minutes to check for new activity. I have tried putting this part in on_ready, but this seems to stop the execution of any commands, so I had to create a thread. However, when I try to run this code, and there is new activity to send a message about, it raises a RuntimeError:
Exception in thread Thread-1:

推荐答案
async def start():
await bot.wait_until_ready()
# Whatever function you want
bot.loop.create_task(start())
