I just had my students write this program in my CS0 class:
from graphics import *
graphics()
while 0 < 1:
click = mouse()
x = click[0]
y = click[1]
oval([x-10, y-10], [x+10, y+10])
(Note that graphics is Zelle's version with my procedural wrappers
appended, http://www.lclark.edu/~drake/courses/cs0/graphics.py)
Usually (but, frustratingly, not every run), the mouse clicks are
offset, so the circles appear some distance above and to the left of
where they should.
Has anyone else run into this? Is there an explanation or workaround?
