Hello,
I am a psychology student at University of Chicago conducting a survey
on animals, technology, and nature. It takes only 5-10 minutes to
complete and every 20th participant will be emailed a $20 gift
certificate to Barnes & Noble. This should be an interesting
opportunity to learn things
Hi all
I don't understand why I get this error. I'm trying to delete the existing
points, then redraw them after this bit of code to 'animate' my simulation.
def update(self, point1, point2):
# Deletes existing points
if self.point1:
self.w.delete(point1)
