Multi windows in tkinter buttons not responding correctly

[Barrowman]

I haven't been using classes myself but looking at this and other ( working ) examples of code I think you need a change:

[snip]

to this:

 class Fireplace@
   def __init__(self):

       if (bus1.read_pin(15) == 1):
          bus1.write_pin(15, 0)
          Mainfloor.toggleButton1["text"] = ("Fireplace On")
        
       else:Mainfloor
               bus1.write_pin(15, 1)
               Mainfloor.toggleButton1["text"] = ("Fireplace Off")

Of course I may be wrong as I usually am  

 class Fireplace@

The class keyword starts a definition block, and like all other block structures (def, if, for), it uses a colon at the end of the line, not an @.

Mainfloor.toggleButton1["text"] = ("Fireplace On")

The Mainfloor class, itself, does not have a toggleButton1, but it's instances do.  So that would throw an error as you're trying to modify something that doesn't exist.

Nice try, though :)

I have no idea where the @ came from! I copied his code and then pasted his code as was and then again but modified it. I hadn't noticed that somehow the : had changed to @
Ah well I said I'm usually wrong.
