Есть ли способ получить доступ к моей переменной guesses_left из класса TimeToGuess, когда мне нужно проверить, закончились ли они догадки

Я создаю базовое приложение для игры в угадайку в Киви, чтобы выучить его основы, но пока не совсем все понимаю. Мне нужно получить доступ к guesses_left, когда я перехожу к следующему экрану (TimeToGuess), чтобы при написании логики удалить догадки, если они угадали неправильно, и в конечном итоге проиграть, если они закончились.

Я уже пробовалустановить атрибут класса TimeToGuess как Guesses, чтобы получить к нему быстрый доступ, но использование canvas.clear () в релизе кнопки, которое также переключается на TimeToGuess, не работает для меня.

вот код файла python: 

from kivy import *
import random
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.screenmanager import ScreenManager, Screen

guesses_left = int()
computer_num = random.randint(1, 10)
user_guess = int()

class WannaPlay(Screen):
    pass


class Guesses(Screen):
    guesses_left = int()


class TimeToGuess(Screen):
        def user_is_guessing(self):
        if user_guess != computer_num:
            guesses_left -= 1


class Winner(Screen):
    pass


class Loser(Screen):
    pass


class ScreenManage(ScreenManager):
    pass


kv = Builder.load_file('guessinggame.kv')


class GuessingGameApp(App):
    def build(self):
        return kv


if __name__ == '__main__':
    GuessingGameApp().run()

Я некоторое время не прикасался к Киви, поэтому не совсем уверен, что это сработает, но если подчиняется базовому ООП, то это должно сработать.

Вы можете просто объявить переменную guesses_left вне определенного класса, сделав ее доступной для всех ваших классов. то есть: 

from kivy import *
import random
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.screenmanager import ScreenManager, Screen

# Initilize here
guesses_left = int()

class WannaPlay(Screen):
    pass


class Guesses(Screen):
    # instead of here
    pass


class TimeToGuess(Screen):
    pass


class Winner(Screen):
    pass


class Loser(Screen):
    pass


class ScreenManage(ScreenManager):
    pass


kv = Builder.load_file('guessinggame.kv')


class GuessingGameApp(App):
    def build(self):
        return kv


if __name__ == '__main__':
    # Or initilize here
    # guesses_left = int()
    GuessingGameApp().run()

Если это не сработает, оставьте комментарий, и я рассмотрю его, когда смогу.
