(python) Telegram bot- how to send messages periodically?

To send messages periodically in a Telegram bot implemented in Python, you can use the python-telegram-bot library along with Python's threading or schedule module. Here's a step-by-step guide on how to achieve this:

Using python-telegram-bot and schedule Module

  1. Install Libraries: First, make sure you have python-telegram-bot installed. You can install it using pip:

    pip install python-telegram-bot

  2. Import Required Libraries: Import the necessary libraries and modules.

    import telegram from telegram.ext import Updater, CommandHandler import schedule import time

  3. Set Up Telegram Bot: Initialize your Telegram bot using python-telegram-bot.

    # Replace 'YOUR_BOT_TOKEN' with your actual bot token obtained from BotFather bot = telegram.Bot(token='YOUR_BOT_TOKEN') updater = Updater(token='YOUR_BOT_TOKEN', use_context=True) dispatcher = updater.dispatcher

  4. Define a Function to Send Messages: Create a function that sends messages to a specific chat ID.

    def send_periodic_message(): chat_id = 'YOUR_CHAT_ID' # Replace with your chat ID message = "Hello! This is a periodic message from your bot." bot.send_message(chat_id=chat_id, text=message)

  5. Schedule Sending Messages: Use the schedule module to schedule the execution of the send_periodic_message function at regular intervals.

    # Schedule the message to be sent every day at 9 AM schedule.every().day.at("09:00").do(send_periodic_message) # You can add more schedules as needed # schedule.every().hour.do(send_periodic_message) # schedule.every(30).minutes.do(send_periodic_message)

  6. Run the Bot: Start the bot and run it continuously to execute scheduled tasks.

    updater.start_polling() while True: schedule.run_pending() time.sleep(1)

Explanation

  • Bot Initialization: Initialize the Telegram bot using telegram.Bot and Updater from python-telegram-bot. Replace 'YOUR_BOT_TOKEN' with your actual bot token obtained from BotFather.

  • Sending Messages: Define a function send_periodic_message that sends a predefined message ("Hello! This is a periodic message from your bot.") to a specified chat ID ('YOUR_CHAT_ID'). Replace 'YOUR_CHAT_ID' with the chat ID where you want to send the messages.

  • Scheduling: Use schedule.every().<interval>.do(send_periodic_message) to schedule the execution of send_periodic_message at specified intervals (every day at 9 AM in the example). You can customize the interval as needed (hourly, every 30 minutes, etc.).

  • Running the Bot: Start the bot using updater.start_polling() and continuously run the bot while allowing schedule.run_pending() to handle scheduled tasks.

Notes

  • Ensure your bot has the necessary permissions and is added to the chat where you want to send messages.

  • Handle errors and exceptions gracefully, especially when working with scheduling and messaging to ensure reliability.

This approach allows you to send messages periodically using a Telegram bot in Python using python-telegram-bot and schedule. Customize the message content, scheduling intervals, and other parameters based on your bot's requirements and use case.

Examples

  1. Python Telegram bot send message every hour

    • Description: Setting up a Telegram bot in Python to send messages periodically, specifically every hour.
    • Code:
      import time from datetime import datetime, timedelta import telebot bot = telebot.TeleBot('YOUR_TELEGRAM_BOT_TOKEN') def send_periodic_message(): while True: now = datetime.now() if now.minute == 0: # Send message at the start of every hour chat_id = 'YOUR_CHAT_ID' bot.send_message(chat_id, "This is a message sent every hour.") time.sleep(60) # Check every minute if __name__ == "__main__": send_periodic_message()
    • Explanation: This script uses the telebot library to create a Telegram bot. It checks the current time every minute (time.sleep(60)) and sends a message when the minute is 0, indicating the start of a new hour.

  2. Python Telegram bot schedule messages

    • Description: Implementing a Python script for scheduling messages to be sent at specific times using a Telegram bot.
    • Code:
      import sched import time import telebot bot = telebot.TeleBot('YOUR_TELEGRAM_BOT_TOKEN') def send_scheduled_message(message, chat_id, delay): scheduler = sched.scheduler(time.time, time.sleep) scheduler.enter(delay, 1, bot.send_message, kwargs={'chat_id': chat_id, 'text': message}) scheduler.run() if __name__ == "__main__": chat_id = 'YOUR_CHAT_ID' message = "Scheduled message example." delay = 10 # Delay in seconds before sending the message send_scheduled_message(message, chat_id, delay)
    • Explanation: Using the sched module, this script schedules a message to be sent after a specified delay (delay in seconds). The bot.send_message function is called by the scheduler to send the message to the specified chat_id.

  3. Python Telegram bot send message every day

    • Description: Creating a Python script to send messages daily via a Telegram bot.
    • Code:
      import time from datetime import datetime, timedelta import telebot bot = telebot.TeleBot('YOUR_TELEGRAM_BOT_TOKEN') def send_daily_message(): while True: now = datetime.now() if now.hour == 9 and now.minute == 0: # Send message at 9:00 AM daily chat_id = 'YOUR_CHAT_ID' bot.send_message(chat_id, "Good morning! This is your daily message.") time.sleep(60) # Check every minute if __name__ == "__main__": send_daily_message()
    • Explanation: This script sends a daily message at 9:00 AM (now.hour == 9 and now.minute == 0). Adjust the conditions (now.hour and now.minute) to change the time when the daily message should be sent.

  4. Python Telegram bot send message every Monday

    • Description: Writing a Python script for a Telegram bot to send messages every Monday.
    • Code:
      import time from datetime import datetime, timedelta import telebot bot = telebot.TeleBot('YOUR_TELEGRAM_BOT_TOKEN') def send_weekly_message(): while True: now = datetime.now() if now.weekday() == 0 and now.hour == 12 and now.minute == 0: # Send message every Monday at 12:00 PM chat_id = 'YOUR_CHAT_ID' bot.send_message(chat_id, "Happy Monday! This is your weekly message.") time.sleep(60) # Check every minute if __name__ == "__main__": send_weekly_message()
    • Explanation: This script sends a message every Monday (now.weekday() == 0) at noon (now.hour == 12 and now.minute == 0). Adjust now.weekday() to change the day of the week when the message should be sent (0 is Monday, 1 is Tuesday, and so on).

  5. Python Telegram bot send message every X minutes
