Build & Deploy a Telegram Bot with short-term and long-term memory

In this article, using Telegram and Python, I will show how to build a friendly Bot with multiple functions that can chat with question-answering conversations (short-term information) and store user data to recall in the future (long-term information). All this started because a friend of mine yelled at me for not remembering her birthday. I don't know if that has ever happened to you. So I thought I could pretend I remember birthdays while I actually have a Bot doing it for me. Now I know what you're thinking, why building something from scratch instead of using one of the millions of calendar apps around?
