无法使用 discord.py 向 Discord 发送消息

Question

I'm trying to simply create a function that sends a discord message to a specific channel when the bot runs. I want to later call this function in a separate python script. The code below seems to run fine, and the bot appears online - but it is fails to send the message:

import discord

client = discord.Client()
client.run("ABCDeFGHIjklMNOP.QrSTuV-HIjklMNOP") # the token

@client.event
async def on_ready():
    logs_channel = client.get_channel(12345689123456789) # the channel ID
    await logs_channel.send("Bot is up and running")
on_ready()

I'm sure I'm missing something basic but I cannot figure out what it is. I've tried a similar function in Node.js and it works fine however, I would prefer the bot to work in python. Discord.py is up to date, python is v3.10. Any help would be greatly appreciated.

Client.run is a blocking call, meaning that events registered after you call it won't actually be registered. Try calling Client.run after you register the event, as in:

import discord

client = discord.Client()

@client.event
async def on_ready():
    logs_channel = client.get_channel(12345689123456789) # the channel ID
    await logs_channel.send("Bot is up and running")

client.run("ABCDeFGHIjklMNOP.QrSTuV-HIjklMNOP") # the token

You also probably do not want to be manually calling an event handler. If you want to send a message by calling a function, you probably want to consider writing a separate function to the event handler.
