Dear Kristen, Sorry, don't know the context of your code, but I note that you are checking if self.point1 is defined, and if so, try to delete point1 (which is a different variable).
Also, self.point1/point1 may be defined, but may not correspond to an existing tk widget. The error message suggests that you are trying to delete a widget (.44593760) which has already been deleted.
