How to Send a Looped Message in discord.py: A Beginner's Guide

If you're diving into the world of Discord bots with discord.py, you might encounter some challenges along the way. One common task is creating a bot that sends a message in a loop after a command is invoked, and stops when another command is triggered. Here, we will walk through the solution to resolve a common issue you might face: making messages send every 10 seconds without errors.

The Problem

You want your bot to send a message every 10 seconds after users issue a command, let's say h!start, and stop the message loop when they type h!stop. However, you may notice that while trying to implement this, your bot encounters errors and doesn’t send any messages at all.

Common Errors:

The callback for the start command is missing required parameters.

The channel is not defined when you attempt to send messages.

In the following sections, we’ll go through how to effectively create this looping message bot and resolve these issues.

The Solution

Step 1: Setting Up the Command

First, ensure you have a way for the bot to register the channel in which the command was sent. You can achieve this by using the context (ctx) parameter. Here’s how to modify your command:

Step 2: Defining the Message Loop

Next, you’ll need to update your reminder task. This task will retrieve the channel using the stored start_channel variable, ensuring that the bot knows where to send the messages:
