Build a Discord Bot with Python — Slash Commands + Cogs (Beginner Tutorial 2025)

In this beginner-friendly tutorial, you’ll build a Discord bot with Python using discord.py v2, slash commands, and cogs—the simplest scalable structure. We’ll go from zero to a working bot with /ping, /echo, and /roll, plus instant dev-guild sync, safe token management with .env, and minimal intents. What you’ll learn - Creating a Discord application & bot (Developer Portal) - Installing Python & setting up a virtual environment - Using discord.py v2 with slash commands - Adding cogs for clean, scalable command organization - Keeping secrets out of code with python-dotenv - Dev-guild vs global command sync (and why global can be slow) - Common fixes for “commands not showing” and permission issues Commands we build /ping — quick health check /echo — repeat your text /roll n m — roll n dice with m sides Requirements Python 3.11+ A Discord account and a test server If this helped, like 👍, subscribe, and tell me in the comments which feature you want next (embeds, cooldowns, moderation, or a database).
