How to properly implement state storage?

Question

Python

I am writing a bot for a telegram chat messenger.
Technologies: python (django, telepot), heroku The
bot will have quite extensive functionality, and it seems to me that it is convenient to assign some kind of state to each user and change it according to the next user message or other event.
The question is, what is the best way to store this state? Stack? Or did I go completely wrong and should I reconsider the architecture?
UPD: an example of states as I see them:

Answer 1

If the nesting is large, then the stack. If it’s small, then it’s probably better not to bother with the stack, but to do something like a context.

Answer 2

The usual mechanism of sessions, as on sites.
