Radiobutton變量不會改變Python中的值（TKinter）

Question

我正在開展一項針對大學的活動，並堅持另一個問題。我在網上獵殺，但是它沒有告訴我我做錯了什麼。我們必須創建12個箱子，每個箱子下面有一個單選按鈕，每個欄目下有3個欄目，每個欄目都有一個單選按鈕。當選擇單選按鈕時，箱子的顏色就會改變。當單選按鈕未被選中時，它們意味着回到原來的顏色。

在添加我的if語句以確定單選按鈕的變量值後，什麼也沒有發生。

這裏是我的代碼：

# Import the Tkinter functions 
from Tkinter import * 

# Create a window 
the_window = Tk() 
the_window.geometry('460x200') 

# Give the window a title 
the_window.title('Show Columns') 

#Declare Radio Variable 
radio_var = IntVar(value=0) 

#Change first set colour 
def change_first_set_colour(): 

    #Determine colour to display 
    if radio_var == 1: 
     label1.configure(bg="blue") 
     label2.configure(bg="blue") 
     label3.configure(bg="blue") 
     label4.configure(bg="blue") 
    else: 
     label1.configure(bg="grey") 
     label2.configure(bg="grey") 
     label3.configure(bg="grey") 
     label4.configure(bg="grey") 

#Change first set colour 
def change_second_set_colour(): 

    #Determine colour to display 
    if radio_var == 2: 
     label1.configure(bg="blue") 
     label2.configure(bg="blue") 
     label3.configure(bg="blue") 
     label4.configure(bg="blue") 
    else: 
     label1.configure(bg="grey") 
     label2.configure(bg="grey") 
     label3.configure(bg="grey") 
     label4.configure(bg="grey") 

#Change first set colour 
def change_third_set_colour(): 

    #Determine colour to display 
    if radio_var == 3: 
     label1.configure(bg="blue") 
     label2.configure(bg="blue") 
     label3.configure(bg="blue") 
     label4.configure(bg="blue") 
    else: 
     label1.configure(bg="grey") 
     label2.configure(bg="grey") 
     label3.configure(bg="grey") 
     label4.configure(bg="grey") 

#Create label1 
label1 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label1.place(x=5, y=5) 

#Create label2 
label2 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label2.place(x=5, y=45) 

#Create label3 
label3 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label3.place(x=5, y=85) 

#Create label4 
label4 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label4.place(x=5, y=125) 

#Create Radio Button 1 
Radio_1 = Radiobutton(the_window, 
         text="First", 
         variable=radio_var, 
         command=change_first_set_colour, 
         value=1) 
Radio_1.place(x=50, y=165) 

#Create label5 
label5 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label5.place(x=155, y=5) 

#Create label6 
label6 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label6.place(x=155, y=45) 

#Create label7 
label7 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label7.place(x=155, y=85) 

#Create label8 
label8 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label8.place(x=155, y=125) 

#Create Radio Button 2 
Radio_2 = Radiobutton(the_window, 
         text="Second", 
         variable=radio_var, 
         command=change_second_set_colour, 
         value=2) 
Radio_2.place(x=180, y=165) 

#Create label9 
label9 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label9.place(x=305, y=5) 

#Create label10 
label10 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label10.place(x=305, y=45) 

#Create label11 
label11 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label11.place(x=305, y=85) 

#Create label12 
label12 = Label(the_window, bg="grey", fg="black", width=20, height=2) 
label12.place(x=305, y=125) 

Radio_3 = Radiobutton(the_window, 
         text="Third", 
         variable=radio_var, 
         command=change_third_set_colour, 
         value=3) 
Radio_3.place(x=345, y=165) 

#---------------------------------------------------------------- 

# Start the event loop to react to user inputs 
the_window.mainloop() 

任何幫助，將不勝感激！ 謝謝

radio_var是一個對象。您需要使用radio_var.get()才能檢索這些值。
