[Tutor] Creating arbitrary number of destinations. (GUI program)

[Mic]

Hi again :)
First of all, I thought the topic name was correct. Arbitrary means as many 
as one would like or a realistic number right?

I am back with one of my TKinter programs and with new questions:

I have written a program where you can book train tickets. At first , there 
were only a fixed number of seats availible to book, but I have now manged 
to
create as many seats as I would like. That's nice. However, this was only 
for one destination. I want to be able to have as many destinations as I 
want.
The numbers of seats should be the same for every destination.

I sat the entire evening and afternoon trying to get it to work yesterday, 
but I have no idea on how to accomplish this. I tried using for i in range() 
and while loops, without success sadly.
Here is the code so far. I translated all variable name and function names 
to English, so sorry if I missed something.


from tkinter import*
import tkinter as tk
import os
NUMBEROFCHAIRS=32

class ChooseDestinationWindow(Frame):
    def __init__(self,master):
        super(ChooseDestinationWindow,self).__init__(master)
        self.grid()
        self.create_different_destinations()

    def create_different_destinations(self):
        self.destination1=Button(self, 
text="Destination1",command=self.Destination1_function)
        self.destination1.grid()

        self.destination2=Button(self, text="Destination2")
        self.destination2.grid()

        self.destination3=Button(self,text="Destination3")
        self.destination3.grid()

    def Destination1_function(self):
                 class Seats_Destination1(tk.Button):
                      def __init__(self,master,index):
                           text=str(index+1)
                           self.OCCUPIED="red"
                           self.FREE="green"
                           super(Seats_Destination1, self).__init__(master,
                                          text=text, bg=self.FREE,
                                          command=self.PressedChair)
                           self.filename2 = 
"Destination1{}.txt".format(index+1)
                           self.occupied = False

                           if os.path.exists(self.filename2):
                                self["bg"]=self.OCCUPIED
                                self.OCCUPIED=True


                      def PressedChair(self):
                           self.occupied = not self.occupied
                           if self.occupied:
                                self["bg"] = self.OCCUPIED
                                text_file=open(self.filename2,"w")
                                text_file.write(self.filename2)
                                text_file.close()
                           else:
                                self["bg"] = self.FREE
                                try:
                                    os.remove(self.filename2)
                                except:
                                    pass



                 class Destination1_Chairs(Frame):
                      def __init__(self,master):
                           super(Destination1_Chairs,self).__init__(master)
                           self.grid()
                           self.Create_Chairs()

                       Satt till 32.
                      def Create_Chairs(self):
                           for index in range(NUMBEROFCHAIRS):
                                button = Seats_Destination1(self, index)
                                row, column = divmod(index, 4)
                                button.grid(row=row, column=column)
                 root=Tk()
                 root.title("Booking Window")
                 app=Destination1_Chairs(root)
                 root.mainloop()







root=Tk()
root.title("Choose your destination")
root.geometry("900x200")
app=ChooseDestinationWindow(root)
root.mainloop()




Thanks for your time and help!
