How to run Python bot as a service in Ubuntu Linux?

I like building Python bots. Especially for telegram – I think this messenger is very relevant and convenient. All the time of development, debugging and working process of the bots was been on my home server with Windows OS.
But I live and work in Ukraine and fucking russian invaders destroys the energy infrastructure of the country. My UPS is enough for 8 hours of server and network equipment operation in a situation when electricity is down. But I would prefer to spend this charge for other purposes.
I have a great VPS on vultr.com which I decided to move my bots to. So what is needed for this?
