Creating a bot with discord.py opens up endless possibilities for interaction on your Discord server. But what if you want your bot to respond only to messages that fit a specific pattern? In this guide, we'll explore how to use the on_message event to achieve just that.

The Challenge

You want your Discord bot to get triggered whenever a message sent by any user contains a mixture of integers, characters, and strings, formatted like this example: 122-PG-CSAI-2022. To accomplish this, we need to parse the message and validate its structure against specific rules.
