Install requirements: ``` pip install python-telegram-bot==20.* ``` 2. Set your Telegram bot token as an environment variable: ``` export TELEGRAM_TOKEN=your-bot-token-goes-here ``` 3. Save the script (e.g., `bot.py`) and run: ``` python bot.py ``` # Notes - Never hardcode your token. Use environment variables as shown. - For production, use a database instead of the sample event list. - You can host this bot locally or on platforms like Heroku, railway, etc.
