I'm writing a program that moves the turtle in different directions by pressing down the arrow keys. I want the ability to move it in a particular direction by holding down the respective arrow key instead of pressing it repeatedly. However, when I release the arrow key after holding it down for few seconds, the turtle is moving back a bit instead of stopping immediately. The amount by which it moves back depends on how long I held down the key to move it.

Can you help me to solve this issue or suggest another way to implement this with the turtle module?

Note: I observed that when I hold down the key, the line is not drawn until I release it. I'm not sure if it's expected or related to this issue.

Note 2: I'm using the onkeypress method for handling the "holding down the key" event. I tried using the onkeyrelease(None, arrow\_key) method to solve this, but it doesn't work either.

Here is my code:

```
from turtle import Turtle, Screen

def move_right():
    turtle.setheading(0)
    turtle.forward(25)

def move_up():
    turtle.setheading(90)
    turtle.forward(25)

def move_left():
    turtle.setheading(180)
    turtle.forward(25)

def move_down():
    turtle.setheading(270)
    turtle.forward(25)

turtle = Turtle()
screen = Screen()

screen.onkeypress(move_right, "Right")
screen.onkeypress(move_up, "Up")
screen.onkeypress(move_left, "Left")
screen.onkeypress(move_down, "Down")
screen.listen()
screen.exitonclick()

```
