How to Create a Python Discord Bot?

Estimated read time 2 min read

To create a Discord bot in Python, you can use the Discord.py library, which provides a convenient API for interacting with the Discord API. Here are the general steps to create a Discord bot:

  1. Create a Discord application and bot account through the Discord Developer Portal.
  2. Install the Discord.py library using pip.
  3. Create a Python script that connects to the Discord API using the Discord.py library, logs in as the bot account, and performs actions.
  4. Use the Discord.py library to listen for events and respond appropriately.

Here’s an example implementation of a simple Discord bot that responds to user messages:

import os
import discord
from dotenv import load_dotenv

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

client = discord.Client()

@client.event
async def on_ready():
    print(f'{client.user.name} has connected to Discord!')

@client.event
async def on_message(message):
    if message.author == client.user:
        return

    if message.content.startswith('!hello'):
        await message.channel.send('Hello!')

client.run(TOKEN)

In this implementation, we start by importing the necessary libraries: os, discord, and dotenv. We then use the load_dotenv function from the dotenv library to load the Discord bot token from a .env file. This is a common practice to keep the token private and secure.

We then create a Client object from the discord library, and define two event handlers using the @client.event decorator:

  • The on_ready event handler is called when the bot successfully connects to the Discord API, and simply prints a message to the console.
  • The on_message event handler is called whenever a message is sent in a channel that the bot can see. If the message is from the bot itself, we return immediately to avoid an infinite loop. Otherwise, we check if the message starts with the command “!hello”, and respond with “Hello!” if it does.

Finally, we call the run method of the Client object with the Discord bot token to start the bot and connect it to the Discord API.

Note that this is a very simple example of a Discord bot, and you can customize it to handle more complex interactions, use external APIs, and more. Also, it’s recommended to use a Command Handler such as the discord.ext.commands module to manage commands more efficiently.
