Discord bot + python + mongodb how to set validation?

Question

Bots

tell me how to do it right. I need the variable to be checked and the desired result is displayed ,
for example
, I write the .go command, Then the bot assigns $y=1 to the variable, while &y=1 no one else. to 0.
how and where can variables be written so that they are stored there 24/7 and changed as needed? such as one file and all the variables were stored there.
