如何从另一个文件的函数中获取值？Python

Question

有没有人能帮帮我？

我有两个文件，一个叫 game.py，另一个叫 settings.py。我只想从设置文件里拿一个值来用在游戏里，但我不知道我哪里出错了。

我想要的那个值在一个叫 bbbbb 的函数里...

THIS IS MY SETTINGS
from tkinter import*
import game

class Application(Frame):

    def __init__ (self, master):
        Frame.__init__(self,master)
        self.grid()
        self.create_widgets()

    def bbbbb(self):
        self.xr = self.ball_numbers.get()
        print("printing...", self.xr)
        return self.xr        

    def create_widgets(self):

        self.ball_numbers = IntVar()

        Label(self,text = "Select how many balls you wish to play:").grid()

        Radiobutton(self, text = "1 Ball", variable = self.ball_numbers, value = 1, command = self.bbbbb).grid ()
        Radiobutton(self, text = "2 Balls", variable = self.ball_numbers, value = 2, command = self.bbbbb).grid ()
        Radiobutton(self, text = "3 Balls", variable = self.ball_numbers, value = 3, command = self.bbbbb).grid ()


settings_window = Tk()
settings_window.title(" THE BOUNCER  -  Settings")
settings_window.geometry("600x600")
app = Application(settings_window)
settings_window.mainloop()

我需要这个值在一个叫 handling_settings 的类里，具体是在 create_ball_numbers 这个函数里面。

这是我的 game.py 文件：

from livewires import games, color
from tkinter import*
import settings
import random

games.init(screen_width = 735, screen_height = 350, fps = 35)

class Bounce(games.Sprite):
    def update(self):

        if self.right > games.screen.width or self.left < 0: 
            self.dx = -self.dx

        if self.top < 0:
            self.dy = -self.dy

        if self.bottom == 315 and self.overlapping_sprites: 
            self.dy = -self.dy


class Bar_moving(games.Sprite):
    def update(self):   

        self.x = games.mouse.x  
        self.y = 315

class handling_settings():

    self.yr = bbbbb()
    print("printing number from settings  ", self.yr)

    def create_ball_numbers(self):
        print("inside def", self.yr)



def main():

    background = games.load_image("BG.jpg", transparent = False)
    games.screen.background = background

    call = handling_settings()
    call.create_ball_numbers()

    bar_small = games.load_image("bar_small.jpg", transparent = False)
    the_bar_small = Bar_moving(image = bar_small, x = games.mouse.x)

    games.screen.add(the_bar_small)
    games.mouse.is_visible = False
    games.screen.event_grab = True

    games.screen.mainloop()


main()    


I think I am not using on the right way IMPORT on top of the file.... keeping appearing this msg...

File "C:\Users\Bruno\Desktop\DIT\Object Oriented Programming\GAME - Assignment\game.py", line 3, in <module>
    from settings import bbbbb
ImportError: cannot import name bbbbb

如果我单独运行这两个文件，没问题... 但是当我试图在 settings 文件里的 bbbbb 函数中获取这个值时，我就卡住了...
