Редактирование и чтение переменной между сервером Flask и многопроцессорным циклом [дубликат] ⇐ Python

[Anonymous]

У меня работает сервер Flask и работает многопроцессорный цикл. я хочу иметь возможность изменять переменную на сервере фляг и просматривать ее в цикле в операторе if. вот мой код, я удалил много вещей, которые, по моему мнению, не было важно показывать.

переменная, которую нужно изменить, - это toggle (должна быть только 1 или 0)
она изменяется в sms() и используется с оператором if в цикле

# I removed a lot of stuff that i dont think was needed
