What will you learn?

By following this tutorial, you will master the art of sending complete strings from Python to Telegram that contain a specific substring. This skill is invaluable when you need to filter messages before sending them based on specific criteria.

Introduction to the Problem and Solution

When utilizing Python to send messages via Telegram, there are instances where filtering out messages containing a particular substring becomes necessary. In such scenarios, we can achieve this by identifying and isolating messages that meet our specified criteria before transmitting them over Telegram.

To tackle this challenge effectively, we will harness the power of string manipulation techniques in Python in conjunction with the capabilities offered by the python-telegram-bot library. By combining these tools seamlessly, we can develop a solution that sieves through messages based on substrings and forwards only those that align with our defined conditions.

Code

# Importing necessary libraries
import telegram

# Define your token and chat ID (replace 'TOKEN' and 'CHAT_ID' with actual values)
TOKEN = 'your_token_here'
CHAT_ID = 'your_chat_id_here'

# Initialize bot handler
bot = telegram.Bot(token=TOKEN)

# Sample list of strings/messages
messages = ["Hello! #Python is awesome", "Check out this link: https://example.com", "We are learning programming"]

# Filter messages containing '#' before sending them
for message in messages:
    if '#' in message:
        bot.send_message(chat_id=CHAT_ID, text=message)

Explanation

In the provided code: – We import the telegram library for Telegram interaction. – Bot token and chat ID are defined (ensure to replace placeholders). – A list of sample messages is created. – The loop checks each message for the presence of ‘#’ before dispatching it via the Telegram bot using bot.send_message().

This methodology guarantees that only messages containing the specified substring are transmitted through Telegram.

    How do I obtain my Telegram Bot Token?

    You can generate a new bot on Telegram through BotFather, which furnishes you with a unique API token for your bot.

    Can I use other symbols or substrings for filtering besides ‘#’?

    Absolutely! You have the flexibility to adjust the conditional check (if ‘#’ in message) as per your filtering requirements.

    Is it possible to send different types of content like images or files using this method?

    Certainly! Besides text-based messages, you can share multimedia content like images or documents through your Python script leveraging appropriate methods within python-telegram-bot library.

    What happens if my chat ID is incorrect or invalid?

    It’s imperative to ensure accuracy in your chat ID; otherwise, message delivery by your bot may face obstacles.

    Can I apply additional formatting or styling to my outgoing messages?

    Yes, you have options for applying markdown formatting when sending text-based content through your bot; refer to official documentation for more details.

    Do I need an internet connection at all times while running this script?

    Yes, since this script interacts with external services like Telegram’s API servers, an active internet connection is mandatory during execution.
