Yes, Python can absolutely be used for creating Discord bots. Python is one of the most popular and commonly used programming languages for Discord bots due to its simplicity, flexibility, and extensive library support.
What is a Discord bot?
A Discord bot is an automated program that interacts with the Discord messaging platform. Bots can be programmed to respond to messages, moderate conversations, play music, provide information, and perform many other helpful tasks for your Discord server.
Bots connect to the Discord API and are controlled by code running on a server or computer. When configured, bots appear as their own user profiles in your server with a distinct name and avatar.
Why use Python for Discord bots?
Here are some of the key reasons why Python is a great choice for building Discord bots:
- Easy to learn syntax – Python has a simple, readable coding style that is easy for beginners to pick up.
- Extensive libraries – Python has many robust libraries designed specifically for interfacing with Discord’s API in an efficient way.
- Fast development time – Python allows developers to build and iterate Discord bots quickly.
- Cross-platform support – Python code can run on Windows, Mac, Linux, and more.
- Active community – There are many Python developers and resources available for help building Discord projects.
- Supports asynchronous code – Python’s async/await syntax is perfect for the asynchronous nature of Discord bots.
Python Discord bot libraries
While it’s possible to use Python’s built-in libraries to interact with the Discord API, several purpose-built third-party libraries exist to make Discord bot creation even easier. Here are some of the most popular Python libraries for Discord bot development:
discord.py
One of the most fully-featured and widely-used Python libraries for Discord bots is discord.py. Key features of discord.py include:
- Intuitive object-oriented interface
- Functions for managing servers, channels, members, messages
- Support for commands, events/hooks, tasks
- Voice chat and music playback capabilities
- Easy creation of rich embeds
Pycord
Pycord is a fork of discord.py designed to be more extensible and scalable. Advantages of Pycord include:
- Improved event system
- Enhanced rate limit handling
- Better support for plugins/extensions
- Drops support for Python 3.5
disnake
disnake is another popular fork of discord.py focused on stability and performance improvements like:
- Faster caching
- Lower memory usage
- Built-in support for component interactions
- Improved reliability
Hikari
Hikari is a lightweight, high-performance Discord bot library designed specifically for speed, efficiency, and scalability. Key features include:
- Rate limit handling
- Built-in support for parallel requests
- Cache for improved performance
- Websocket connection pooling
Creating a basic Discord bot in Python
Let’s go through a quick example of building a simple Discord bot in Python using the discord.py library. This will demonstrate the basics of connecting a Python Discord bot to the API.
1. Import discord.py
First import the discord.py module so we can access its classes and functions:
import discord
2. Create a Bot class
Next we’ll subclass the discord.Client class to create our own Bot class definition:
class MyBot(discord.Client):
# bot definition
3. Create on_ready event
Inside the bot class, we create an on_ready() event handler which will be called when the bot initialized and connects to Discord:
async def on_ready(self):
print(f'Logged in as {self.user} (ID: {self.user.id})')
4. Create bot instance
Next we’ll instantiate our bot object, passing in a token for authorization:
bot = MyBot()
bot.run("TOKEN")
We just need to call bot.run() passing in a valid token to connect our bot to Discord!
Advanced Discord bot capabilities
This simple example demonstrates the basics of connecting a Python Discord bot to Discord. But there are many more advanced capabilities we can add to create a feature-rich bot, such as:
Commands
Handling chat commands with the @bot.command() decorator. Commands allow users to interact with your bot by calling specific functions.
Events
Responding to Discord events like reactions, edits, member joins, etc using @bot.event decorators.
Music Playback
Playing music in voice channels by streaming audio from YouTube or other sources.
Moderation
Automating moderation with bans, role assignment, cleanup, anti-spam, and more.
Web Dashboards
Integrating web frameworks like Flask to create admin dashboards to control your bot through a web interface.
Database Storage
Storing bot data like settings and memories in a database like PostgreSQL or MongoDB.
Scheduled Jobs
Running cron jobs with apscheduler to automate tasks like backups, updates, and more.
Message Embeds
Generating rich embedded messages with color, images, footers, fields and more.
These are just a fraction of the functions you can add to a Python Discord bot using the powerful discord.py framework and other packages from the Python ecosystem.
Challenges of building Discord bots in Python
While Python is an excellent language choice for Discord bots, there are some challenges to keep in mind during development:
- Handling asynchronous code – Python’s async/await syntax helps but can get complex.
- Potential API timeout/rate limits – Understand Discord’s API limits.
- Scaling to large servers – Ensure your bot design supports many guilds/members.
- Reliability expectations – Users expect bots to have near 100% uptime.
- Updating/deploying new versions – Have a process to push updates without downtime.
- Feature creep – Resist overloading bots with too many commands/features.
- Security and authorization – Safely storing tokens and validating users.
While these issues take some experience and best practices to master, the Python community has many resources to help you create solid Discord bots.
Tips for running Python Discord bots
Here are some tips to follow when running and maintaining Python Discord bots in production:
- Use a virtual environment to isolate dependencies.
- Minimize system resources by only loading required bot extensions.
- Monitor server load and restart periodically to clear memory.
- Use a process manager like PM2 to restart on crashes.
- Consider hosting options like Heroku, AWS, or VPS for reliability.
- Handle unexpected errors and disconnects gracefully.
- Cache data and limit unnecessary API calls.
- Implement sharding when approaching 1000 guilds.
Example Python Discord bots
To get an idea of Python Discord bots in action, here are some examples of popular open source Python Discord bots:
1. SinusBot
SinusBot is a music bot focused on high quality music playback. Features include:
- YouTube and SoundCloud support
- Playlist management

- DJ role based access controls
2. Python Discord Bot
Python Discord Bot is a general purpose utility bot with features like:
- Moderation commands
- Server admin tools
- Trivia/hangman games
- Polls, reminders, and more
3. Discord Mod Mail Bot

Conclusion
Python is an excellent, versatile programming language that excels at building feature-rich Discord bots quickly and efficiently. With its easy syntax, wealth of libraries, and an active developer community publishing many open source examples, Python is an ideal choice for any Discord bot project.
By leveraging libraries like discord.py, Python bots can handle commands, moderate conversations, provide useful information to users through rich embeds, play music in voice channels, and automate server administration via scheduled tasks. While bots do take effort to properly design, secure, deploy and scale, Python’s versatility accelerates the entire development process.
Any developer looking to expand their skills into the domain of chatbot creation will find Python a powerful ally that can bring their bot ideas to life on Discord’s platform. The world of Python Discord bots is rich and exciting – there’s no limit to the helpful bots you can dream up and build!
