Make a Discord Bot with Python - Part 2

Submitted by nanodano on Fri, 02/16/2018 - 19:39

Important note: The discord.py version used here is 0.16.12. The version of Python used is 3.6. Python 3.7 introduced backwards incompatible changes with async. The new version of discord.py 1.0 is also incompatible with this code here. Make sure you follow the instructions closely and ensure you have the proper versions. discord.py==0.16.12, python<3.7.

If you don't already have a Discord server and a bot, you might want to check out Making a Discord Bot in Python - Part 1 which covers how to create a server, create a Discord app, create a bot user, authorize the bot for your server, and test it all with a Python script. This assumes you already have a bot account ready to go.

If you are interested in learning how to make a Discord bot in JavaScript, check out the JavaScript Discord Bot Tutorial and check out all of the other Discord related tutorials on DevDungeon.

If you want to check out some bots that are already made, check out two DevDungeon projects: Chatty Cathy AI chat bot and Help Desk Bot a fun utility bot, both written in Python.

Run pip install from your system terminal/shell/command prompt. Make sure to install the correct version of the package. If you are using PyCharm you can open the terminal from View -> Tool Windows -> Terminal

python -m pip install discord.py==0.16.12
