Lita Cho added the comment: I can make it worth such that it doesn't raise a Terminator error. This works great when working with Turtle on the command line. I basically check if the root exists for all Tk canvas calls. If it got destroyed, then it just returns. However, if you run the follow

Lita Cho added the comment: Oops, pressed submit too soon. Now the programs raise a Terminator exception rather than a TclError, which I think is correct because the programs are calling Turtle methods when the TurtleScreen had been destroyed. I wasn't sure if it was better to return None ra

Lita Cho added the comment: So it looks like the bug fix was really simple. I just needed to set TurtleScreen._RUNNING to True when the screen object tries to get destroyed. -- Added file: http://bugs.python.org/file35462/turtle_crash.patch ___ Pytho

Lita Cho added the comment: So I have a patch that fixes the original problem, but doesn't fix the crash with the tdemo_round_dance.py. However, I was wondering why TurtleScreen._RUNNING = True in the _destroy method. Can anyone shed some light on this? Here is the current state of my patch.

Lita Cho added the comment: I was looking at this more, and from my understanding, the turtle code is continuing to run even when the TK window is destroyed. Thus the crash. It looks like the drawing functions are being made on the fly with the following method: for methodname in _tg_turtle_f

Alexander Belopolsky added the comment: Same error occurs when the python -m turtle demo is interrupted by closing the window. I think the correct fix is to exit when the window is closed, but I cannot figure out the best way to achieve that. This probably should be done at the application/

Alexander Belopolsky added the comment: I have come across the same bug. To reproduce, run Demo/turtle/tdemo_round_dance.py and kill the Tk window before the "dance" stops. The mysterious command name ".10170160" is simply the generated name for the canvas widget - '.' + repr(id(self)). S
