New submission from Alex McNerney <amcnerne...@yahoo.com>:
In Python 2.7 and 2.6 (only ones I have tried), there is a bug in the turtle
module's tracer() function, when applying it to multiple turtles using the same
value.
When two turtles are defined (to draw simultaneously), and both turtles'
tracers are set to the same number, one of the turtles does not end up
following its tracer value. (It's a little hard to explain...look at/try the
sample code)
The following script will recreate this glitch:
"
from turtle import *
t1 = Turtle()
t2 = Turtle()
for t in turtles():
t.ht()
t.speed(0)
t.tracer(10)
t1.color("black")
t2.color("red")
for x in range(500):
t1.forward(x)
t2.forward(x)
t1.left(144.5)
t2.right(144.5)
"
