I can't move turtle in python which for snake game

I'm trying to make a snake game just for fun and learning but I can't move my turtle. When I add the border lines and run it. My turtle can't move a bit. Problem pop up when I add the "if turtle.xcor()>290 or turtle.xcor()<-290 or turtle.ycor()>290 or turtle.ycor()<-290:" border lines

I've checked the lines and searched on the internet but i couldn't find a solution. I'm new so the problem might be easy.

Python Turtle Snake Game: Problems With Snake Segments

As you guessed from the title, I'm making a beginner form of a snake game using the turtle module in Python. So far, everything is running smoothly, except for one single detail; the segments are not attached to the head, but they are rather lying inside the head itself on top of each other (you get what I'm saying?).
Here is what I wrote:
os.system("pause")
import turtle
import random
#Game Screen Set Up
screenWidth = 600
screenHeight = 600
screencolor = "#221C35"
screentitle = "Snake Game for Beginners"
screen = turtle.Screen()
screen.setup(width=screenWidth, height=screenHeight)
screen.bgcolor(screencolor)
screen.title(screentitle)
screen.tracer(0)
#Game Objects
head = turtle.Turtle()
head.speed(0)
head.shape("square")
head.color("#FFFFFF")
head.penup()
head.goto(0, 0)
head.direction = "stop"
food = turtle.Turtle()
food.speed(0)
food.shape("square")
food.color("#888888")
food.penup()
food.goto(0, -40)
segments = []
#Game Functions
def upwards():
head.direction = "up"
y = head.ycor() + 20
head.sety(y)
def downwards():
head.direction = "down"
y = head.ycor() - 20
head.sety(y)
def right():
head.direction = "right"
x = head.xcor() + 20
head.setx(x)
def left():
head.direction = "left"
x = head.xcor() - 20
head.setx(x)
#Keyboard Bindings
screen.listen()
screen.onkeypress(upwards, "Up")
screen.onkeypress(downwards, "Down")
screen.onkeypress(right, "Right")
screen.onkeypress(left, "Left")
while True:
screen.update()
if head.distance(food) < 20:
food.goto(random.randint(-290, 290), random.randint(-290, 290))
new_segment = turtle.Turtle()
new_segment.speed(0)
new_segment.shape("square")
new_segment.color("white")
new_segment.penup()
segments.append(new_segment)
for index in range(len(segments)-1, 0, -1):
segments[index].goto(segments[index-1].xcor(), segments[index-1].ycor())
if len(segments) > 0:
x = head.xcor()
y = head.ycor()
segments[0].goto(x, y)
if (head.xcor() > 290) or (-290 > head.xcor()) or (head.ycor() > 290) or (-290 > head.ycor()):
head.goto(random.randint(-290, 290), random.randint(-290, 290))

How do I end a code using Python Turtle Module when getting a Terminator Error

Hello I'm new to python and I do not really know how to fix terminator errors. I tried some other fixes I found around this website but they end up leading to other errors such as .!canvas being an invalid command name.
This is the code

I can't get VSCode to open window for snake script

I am practicing some very simple projects and I found the snake game and handed to try my hand. I am pretty sure I copied the code completely but when I run it a small blue screen pops up for a split second and then disappears and doesn't say what's wrong.

You are getting a blue screen because the code is not complete there are some variables missing + the main game loop doesn't exits so the game simply crashes here is the complete code I got it from the same website further down Full Code

how can i move my snake head with my arrow keys

what did I do wrong because I cant move the snakehead with my wasd key the error that I keep on getting is turtle.terminator, It also say the problem is at the wn update place can u please tell me the solution this move the sane head i tried every thing this always come up raise Terminator
