I need a small Python script that will post the exact same plain-text sentence to my Telegram channel every hour, around the clock. I already have the bot token and channel ID; what’s missing is the code and a brief note on how to keep it running (systemd, PM2, or a simple loop with `time.sleep()`—I’m open, as long as it’s reliable). The message never changes, so there’s no need for databases, files, or randomisation logic. Just call the Telegram Bot API with the text, wait sixty minutes, repeat. Please deliver the `.py` file together with a short readme covering: • how to install any required libraries (I’m fine with `python-telegram-bot`, `aiogram`, or straight `requests`) • how to launch it on Linux so it survives reboots That’s the whole job—clean, concise, and ready for me to drop onto the server and let it run.
