Discord Bot python 理解

Question

I want to understand some basics in the making of a discord bot

# bot.py
import os

import discord
from dotenv import load_dotenv

load_dotenv()
TOKEN = os.getenv('DISCORD_TOKEN')
GUILD = os.getenv('DISCORD_GUILD')

client = discord.Client()

@client.event
async def on_ready():
    for guild in client.guilds:
        if guild.name == GUILD:
            break

    print(
        f'{client.user} is connected to the following guild:\n'
        f'{guild.name}(id: {guild.id})'
    )

client.run(TOKEN

I didn't understand clearly what the @client.event does and how it works, I know its some kind of listener and the function get_ready Is it a function built in the discord.py package bcz apparently its the same name everywhere

Answer 1

Yes, @client.event is a listener. When discord realises that event has occured it will callback this function.

The name on_ready is the sam everywhere because it only makes sense to use it. No, you don't need to use on_ready, you can use anything else but you just need to specify it in the decorator instead.

By default, if you just do @client.event, it will take the name of your function.

@client.event(‘on_ready’)
def anotherfuncname():
