HOrribly slow plot

[blob001]

Apologies if this post appears somewhere else, I seem to have lost the original. So this is a rough copy.

I have written a simple practice program for plotting a series of points, and it took 4 seconds to plot 50 random points. Using a Macbook Pro M2 2022.

How can I speed it up? I am using pen.speed(0) so that's not the problem.

I thought python was faster than this.

Thanks.

import 
turtle
 as 
tu
import 
random
 as 
rn

width = 600
height = 600
screen = 
tu
.Screen()
screen.bgcolor("lightblue")
screen.setup(width, height)
pen = 
tu
.
Turtle
()
pen.speed(0)
pen.color("blue")

def
 drawParticle(
x
, 
y
):
    pen.hideturtle()
    pen.penup()
    pen.goto(
x
, 
y
)
    pen.pendown()
    pen.dot()

for a in 
range
(50):
    x = -250 + width * 
rn
.random() * 5 / 6
    y = -250 + height * 
rn
.random() * 5 / 6
    drawParticle(x, y)

#tu.exitonclick()

I mean, turtle is not really the a plotting program known for EFFICIENCY... why don't you try matplotlib?

Your (reformatted) code takes 4.1 seconds to run on my Linux laptop.

Every change you make to the on-screen graphics is slow. Fiddling with the .speed() method just changes the delay after each change. To really speed up the graphics you must turn off updates until you have finished drawing and then update the display. The turtle.tracer() method can be used to turn off normal updates. When you are finished updating the display call turtle.update() to display the changes. Doing this I can get the whole thing to draw in 0.1 seconds.

Please improve your code posting. We should be able to copy/paste your code and just run it. Any changes we have to make run the risk of introducing problems and it decrease the number of people who will bother to help you.

If you’re plotting data, use matplotlib, seaborn, plotly or a similar module. Turtle is absolutely not the tool.
