First of all, I am no Tkinter expert so [a]some, [b]none or [c]all of this
may be incorrect.

The try..except block that catches the ButtonPush only exsists in __init__.
The button
push event happens in a loop in root.mainloop()--after the Turtle object
exsists--outside
of __init__.

Is there a reason you are using exceptions to catch the button push event?
It seems sort of
convoluted to me. I wonder if you could use a callback instead to
communicate between the classes.

hoping for [a] or [b]
