Tkinter-Checkbutton's variable doesn't change

Hi everyone..

I have a problem coding in python tkinter.The variable of the checkbutton returns ( is) always 0.So I can't know if the user selects each checkbutton or not.
My code is below:

Code:

from Tkinter import *


class First_Opening():
    
    def __init__(self):
        
     
     self.first_open_var1=IntVar()
     self.first_open_var2=IntVar()
     self.list12=[]
     top=Tk()  
     top.title('Program')
     top.resizable(width=FALSE, height=FALSE)
     top.geometry('200x60+200+200')
     top.configure(background='light blue')                                         
     top.option_add("*background", "light blue")

     self.first_open_label6=Label(top,text='Your Choise:')
     self.first_open_label6.place(x=10,y=25)
     self.checkBox1=Checkbutton(top,text='First Choise', command=self.first_open_first, variable=self.first_open_var1)
     self.checkBox1.place(x=90,y=10)
     self.checkBox2=Checkbutton(top,text='Second Choise', command=self.first_open_second, variable=self.first_open_var2)
     self.checkBox2.place(x=90,y=30)



    def first_open_first(self):
       # print "1o",self.first_open_var2.get() 
        if self.first_open_var1.get()==1:
          self.list12.append("First Choice")
         # print self.list12
          self.checkBox2.deselect()
                
    def first_open_second(self):
        #print "2o",self.first_open_var2.get()
        if self.first_open_var2.get()==1:
          self.list12.append("Second Choise")
         # print self.list12
          self.checkBox1.deselect()


form1=Tk()
form1.title=('Something')
form1.resizable(width=FALSE, height=FALSE)
form1.geometry('250x130+200+200')
form1.configure(background='light blue')                                        
form1.option_add("*background", "light blue")

dial_first_opening = First_Opening()
form1.destroy()

form1.mainloop()

What do you think is the problem?

Thanks in advance.

Code:

from Tkinter import *

class First_Opening():
    
    def __init__(self):
     top=Tk()  
     self.first_open_var1=IntVar(top)     # master is a top level that isn't destroyed
     self.first_open_var2=IntVar(top)
     self.list12=[]
     top.title('Program')
     top.resizable(width=FALSE, height=FALSE)
     top.geometry('200x60+200+200')
     top.configure(background='light blue')                                         
     top.option_add("*background", "light blue")

     self.first_open_label6=Label(top,text='Your Choise:')
     self.first_open_label6.place(x=10,y=25)
     self.checkBox1=Checkbutton(top,text='First Choise', command=self.first_open_first, variable=self.first_open_var1)
     self.checkBox1.place(x=90,y=10)
     self.checkBox2=Checkbutton(top,text='Second Choise', command=self.first_open_second, variable=self.first_open_var2)
     self.checkBox2.place(x=90,y=30)
     top.mainloop()                       #**************** run mainloop of top

    def first_open_first(self):
        print "1o",self.first_open_var1.get()   ###### changed to var1
        if self.first_open_var1.get()==1:
          self.list12.append("First Choice")
          print self.list12
          self.checkBox2.deselect()
                
    def first_open_second(self):
        print "2o",self.first_open_var2.get()
        if self.first_open_var2.get()==1:
          self.list12.append("Second Choise")
          print self.list12
          self.checkBox1.deselect()

################if you had needed that other top level you could withdraw rather than destroy it.

dial_first_opening = First_Opening()
