Python. How to store data?

Question

Python

I want to write a function for a telegram bot that would send some message every day at a specific time for each user, depending on the time zone. But for this, I need to first know the chat ID, username and its time zone (for each person). The question is how then to store this data. Dictionary, databases, json, something else?

Answer 1

Depends on how many users and posts per day. If there are less than a million messages, at least store them somewhere. If there are less than a hundred thousand users, the same is true. Maybe even in a shelve
