使用Tkinter從類中返回按鈕的值

Question

這裏我試圖用按鈕選擇一個值。我如何從班級中返回'選項'的值？由於

我想有像my_gui_value = option_box（根）。選項 感謝

from Tkinter import Tk, Label, Button 

class option_box: 
    def __init__(self, master): 
     self.master = master 
     master.title("A simple GUI") 

     self.label = Label(master, text="This is our first GUI!") 
     self.label.pack() 

     self.train_button = Button(master,text="Training",command=self.train) 
     self.train_button.pack() 

     self.test_button = Button(master, text="Testing", command=self.test) 
     self.test_button.pack() 

    def train(self): 
     option=0 
     print option 
    def test(self): 
     option=1 
     print option 

root = Tk() 
my_gui = option_box(root) 
root.mainloop()

保存它，而不是返回它。

def train(self): 
    self.option = 0 
    print self.option 
def test(self): 
    self.option = 1 
    print self.option
