I am trying to run a Tkinter GUI on Python 3.x and When I use the .get command to get the number off a scale, this error pops up
Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python34\lib\tkinter\__init__.py", line 1482, in __call__
    return self.func(*args)
  File "C:\Users\Danny\Downloads\Space RPG. Alpha 0.2 (2) (1).py", line 39, in close
    print (w1.get(), w2.get())
  File "C:\Python34\lib\tkinter\__init__.py", line 2840, in get
    value = self.tk.call(self._w, 'get')
_tkinter.TclError: invalid command name ".52674064"
What is happening?
That usually means that you're trying to call a method on a widget that has been destroyed. The string .52674064 is the internal name of a specific widget. 
This can easily happen if you call a function via a binding or via after, if the widget is destroyed before the binding or after call has been triggered.
tkinter.TclError: invalid command name ".52674064
