How to implement data transfer between players in a Telegram bot?

Question

Bots

Need help. I create a Telegram bot, I need to make sure that the values ​​​​of variables are transferred between the players of the bot. For example, 2 players started playing with each other and one dropped out, for example, 8, and the other 9, you need 1 player to know that the enemy has dropped 9, and the enemy has learned that the player has dropped 8. To create a bot, I use TeleBot.

Answer 1

Do you need to save this data somewhere? And then pass it on to another player.
And where to store it is up to you.
