Problem resizing a window and button placement

[Steve GS]

SOLUTION FOUND!

The fix was to write the code that uses the width value and to place it into the function itself.  
Kluge? Maybe but it works. 

Mischief Managed.

========================
As for the most recent suggestion, it fails for me:

Traceback (most recent call last):
  File "F:/___zInsulin Code A 08-02-23/WinPic/IOWw.pyw", line 14, in <module>
    print("Ww Outside = <" + str(Ww) > + ">")
TypeError: bad operand type for unary +: 'str'

With the need to close the window, it adds an extra step and intervention to the program to use. I am not sure how this help[s.

As a curio, it would be interesting to see how to use the value of a variable, created in the function used here, and make it available to the code outside the function.

root = tk.Tk()
root.bind('<Configure>', on_configure)
root.mainloop()

print("Ww Outside = <" + str(Ww) > + ">")

Produces:
Ww Inside = <200>
Ww Inside = <200>
Ww Inside = <205>
Ww Inside = <205>
Ww Inside = <206>
Ww Inside = <206>
Ww Outside = <206>
