Turtle screen closes almost immediately after opening

Question

I writed some code from a python book and the book shows that if you run the code there will be no problem

but when I ran the code there was a problem

This is my code:

import turtle
import time

turtle.pensize(5)
turtle.bgcolor("black")
turtle.pencolor("white")
turtle.turtlesize(2,2,2)

def ileri():
    turtle.fd(5)
def geri():
    turtle.backward(5)
def sag():
    turtle.right(90)
    turtle.fd(5)
    turtle.left(90)
def sol():
    turtle.left(90)
    turtle.fd(5)
    turtle.right(90)
def sagdon():
    turtle.right(10)
def soldon():
    turtle.left(10)
def siyah():
    turtle.pencolor("black")
def yesil():
    turtle.pencolor("green")
def acikyesil():
    turtle.pencolor("lightgreen")
def mavi():
    turtle.pencolor("blue")
def acikmavi():
    turtle.pencolor("lightblue")
def sari():
    turtle.pencolor("yellow")
def kirmizigul():
    turtle.pencolor("red")

turtle.onkeypress(ileri, "w" or "Up")
turtle.onkeypress(geri, "s" or "Down")
turtle.onkeypress(sag, "d")
turtle.onkeypress(sol, "a")
turtle.onkeypress(sagdon, "Right")
turtle.onkeypress(soldon, "Left")
turtle.onkeypress(siyah, "0")
turtle.onkeypress(yesil, "1")
turtle.onkeypress(acikyesil, "2")
turtle.onkeypress(mavi, "3")
turtle.onkeypress(acikmavi, "4")
turtle.onkeypress(sari, "5")
turtle.onkeypress(kirmizigul, "6")
turtle.listen()

when I try to run this game every hecking time a screen opens for like 0.1 second and closes

if you try to help it will be so good for me

I was expecting the screen was going to be remain open because it was in the books image but I was not expecting to see the screen for just 0.1 seconds

Use turtle.done() at the end of your code and the window will stay until you close it yourself.

The official python wiki page for turtle clearly states that:

(turtle.mainloop) Must be the last statement in a turtle graphics program. Must not be used if a script is run from within IDLE in -n mode (No subprocess) - for interactive use of turtle graphics.

Since your program lacks a call to the mainloop function, it closes as soon as it is runs. All you have to do is add a

turtle.mainloop()
turtle.done()

at the end of your program.

I hope this helps :)

It works but this time it doesn't detect my keybord. But thank you so much for your help — Eral, Feb 13 '23 at 09:29

i believe this is what you tried to do all you had to do is import screen and set the screen setup and update it:

import turtle
from turtle import  Screen
import time

turtle.pensize(5)
turtle.bgcolor("black")
turtle.pencolor("white")
turtle.turtlesize(2,2,2)

screen= Screen()
screen.setup(600,600)

def ileri():
    turtle.fd(5)
def geri():
    turtle.backward(5)
def sag():
    turtle.right(90)
    turtle.fd(5)
    turtle.left(90)
def sol():
    turtle.left(90)
    turtle.fd(5)
    turtle.right(90)
def sagdon():
    turtle.right(10)
def soldon():
    turtle.left(10)
def siyah():
    turtle.pencolor("black")
def yesil():
    turtle.pencolor("green")
def acikyesil():
    turtle.pencolor("lightgreen")
def mavi():
    turtle.pencolor("blue")
def acikmavi():
    turtle.pencolor("lightblue")
def sari():
    turtle.pencolor("yellow")
def kirmizigul():
    turtle.pencolor("red")
while(True):
    screen.update()
    time.sleep(0.07)
    turtle.onkeypress(ileri, "w" or "Up")
    turtle.onkeypress(geri, "s" or "Down")
    turtle.onkeypress(sag, "d")
    turtle.onkeypress(sol, "a")
    turtle.onkeypress(sagdon, "Right")
    turtle.onkeypress(soldon, "Left")
    turtle.onkeypress(siyah, "0")
    turtle.onkeypress(yesil, "1")
    turtle.onkeypress(acikyesil, "2")
    turtle.onkeypress(mavi, "3")
    turtle.onkeypress(acikmavi, "4")
    turtle.onkeypress(sari, "5")
    turtle.onkeypress(kirmizigul, "6")
    turtle.listen()
    screen.exitonclick()

hope it was usefull to you and goodluck.
