Подкатегории в телеграмм боте Как правильно сделать?

Question

[stopparty]

Доброй ночи!
Прошу Вас помощи, есть телеграмм бот
Мне нужно убрать раздел ассортимент, перед ним наделать категории, а потом уже в те категории добавлять товар, столько усилий проделал, все безрезультатно, то python ругается
то кнопки в боте перестают работать

python3 functions.py
