How to minus a variable in pytelegrambotapi?

Question

Python

Good day everyone!

I create a telegram bot and pytelegrambotapi

Almost did everything

There is a variable "balanc" and in it I put the number 10, in short it's like this: ballanc = 10

And I made this function for the bot

if call.data == 'four':
    if balanc <= 10:
         balanc - 10
         bot.answer_callback_query(call.id, "Ты купил кролика")
     elif balanc > 10:
          bot.answer_callback_query(call.id, "У вас не достаточно денег")

There is also a "personal account" button where I can see my balance. But even if I press the "four" button on the callback, the balance does not change. Why didn't they minus 10 from the balanc variable?

Thanks in advance

Answer 1

Not Abalanc - 10
balanc -= 10

Answer 2

Another "bot writer", you don't need to make bots, but learn the basics of python, and programming in general.
