background_task.py not showing messages - Python

Question

I noticed that when I ran a code snippet from the discord.py Github page it didn\'t show the intended message.

My slightly modified code:

import discord
         


        

Answer 1

The code fails because self.get_channel(1234567890) is used before the bot has properly connected, resulted in it always returning None. This is because client = MyClient() is done first, meaning the background task is created but the bot has not yet connected, which is done through client.run.

To fix this, move the creation of the loop to inside the on_ready event.

import discord
import asyncio

import nest_asyncio
nest_asyncio.apply()

class MyClient(discord.Client):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

    async def on_ready(self):
        print('Logged in as')
        print(self.user.name)
        print(self.user.id)
        print('------')

        # create the background task and run it in the background
        self.bg_task = self.loop.create_task(self.my_background_task())

    async def my_background_task(self):
        counter = 0
        channel = self.get_channel(1234567890) # channel ID goes here
        while not self.is_closed():
            counter += 1
            await channel.send(counter)
            await asyncio.sleep(10) # task runs every 10 seconds


client = MyClient()
client.run('token')
