How to create a system for blocking a user by id in a telegram bot through the sqlite3 database?

Question

Python

For example: I write /ban 198468345
Then this id gets into the list of blocked. I think it's pretty easy to do this.

Answer 1

1.Make a table with banned users.
2.At the ban command, add user data.
3.When new messages in the bot, check if its id is in this table.
