Методы вызова из класса Не работает

Question

Я сделал игру поиска сонара и некоторые функции для нее. Я включил эти функции в класс, и теперь хочу называть их, чтобы я мог играть в игру, однако, когда я определяю вызов класса, он теперь возвращает мне что-то вроде game.getNewBoard() принимает 0 позиционных аргументов и говорит мне, что у меня есть учитывая его один, когда у меня нет и так далее. Любая помощь будет оценена по достоинству.

Answer 1

Каждый метод класса в Python получает экземпляр, который он вызывается из первого параметра автоматически. Это означает, что первый параметр всегда равен self:

def drawBoard(self, board):
