How to find out that a user has blocked your bot in telegram?

Question

Python

Hello!
I wrote a bot that uses a database, and once in a while runs through it and loads data for users. But if the user deleted the bot, he would still go over it in the database. Is there any way to know that the user has blocked the bot and remove it from the database?
Thank you!
