How to Asynchronously Send Images with a Telegram Bot in Python

If you're using a Telegram bot to send images to a large number of users, you may have encountered a frustrating delay in delivery times. For example, sending an image to 200 users could potentially take up to 40 seconds, which is far from ideal. The good news is that you don't have to stick with this delay! In this guide, we will explore how to send images more efficiently using asynchronous programming in Python.

Understanding the Problem

When you send messages to users sequentially, your bot waits for each message to be sent before moving to the next one. This creates a cumulative delay if you're sending to a large number of users. In your current implementation, whether you're using the standard Telebot or the asynchronous version, the time taken to send images remains substantial:

Standard Approach: Approximately 40 seconds to send images to 200 users

Using aiogram: Slightly improved, but still around 38 seconds

Given that Telegram limits you to 30 messages per second, using asynchronous programming techniques can help optimize your sending process, breaking the bottleneck and improving efficiency.

Solution: Using asyncio to Send Images

Step-by-Step Implementation

Import Required Libraries: Make sure to import asyncio along with the AsyncTeleBot.

Set Up Your Bot: Initialize your AsyncTeleBot with your API token.

Create the Message Handler: Define the function that handles incoming messages in an asynchronous manner.

Create and Gather Tasks: For each user ID, you will create a sending task and gather those tasks at once to execute them concurrently.

Sample Code

Here is a complete example that demonstrates these steps:

Explanation of Code

Performance Monitoring: The time for sending messages is measured and printed to give you an idea of how much time was saved.

Conclusion

By leveraging the power of asynchronous programming with asyncio, you can significantly reduce the time it takes to send images to multiple users in your Telegram bot. This setup is not just efficient but also scales better with larger user bases. If you have any further tweaks or additional techniques for faster image delivery, feel free to share your insights!

Implementing these changes will make your bot more proficient, allowing you to provide a better experience for your users.
