Правила длины змеи - snakepygame
Я пытаюсь сделать змеиную игру для школьного проекта в pygame, но мне трудно понять, как заставить змею расти. Не ища самый эффективный код, а просто способ сделать это. Кроме того, я не ищу целый переписанный проект или что-то еще, я хочу, чтобы это была моя собственная работа, просто ищу метод, как я могу решить эту проблему. Я знаю, что это будет включать в себя циклический список и, возможно, еще один класс, но это то, что у меня есть до сих пор:

Что я уже пробовал:
Я пробовал добавлять в списки и использовать для циклов, но мне не везет.
