Как сохранить значение флажка в базе данных в python (Tkinter)

Question

В этом коде значение флажка хранится, но в форме 1 0, но я хочу сохранить строку

Я пытался сохранить флажок через "INSERT INTO", но после того, как метод .get () срабатывает, записывается ноль и единица в базу данных, как я могу решить эту проблему?

При запуске программы она записывает нули в переменную, хотя если флажок активен.
