Yes, perhaps that is a good way to go. I didn't think about that.

No, I didn't mean that it have to work online. It is just fine if it works 
on the desktop.
I can only imagine how much more complicated things would be then. But if I 
understood it correctly,
with the help and information I got from you in this mail and in your 
previous mail, I can manage to
solve my problems? It is a bit hard right now to understand, because I am 
unfamiliar with using tuples/lists
and data tables. I will do my best to get it to work.

I just got my program to work today, but I want to shorten the code
using your suggestions in this and your previous email. I still find this 
hard
to do because that way of thinking is completely new to me. I have one of 
these functions
below for each chair. I just want to use one instead of so many functions. 
That is why I am trying to understand and
implement your suggestions.

def chair1_clicked(self):
       """This method runs if chair one is clicked"""

       def change_chair1_value():
           global chair1_value
           button2_value=not chair1_value

       chair1_clicked ()

       if chair_value:

           self.chair1.configure(bg="yellow")
           text_file=open("Hamburg_Dortmund20_00","w")
           text_file.write("Hamburg-Dortmund")
           text_file.close()



           def chair_color_red():
               global chair1_color
               chair1_color=("yellow")
           change_button2_color_red()




       else:
           self.chair1.configure(bg="green")
           os.remove ("Hamburg_Dortmund20_00")




           def chair1_color_green():
               global chair1_color
               chair_color=("green")
           chair1_color_green()
