Continue by adding the following lines:

while True:
    wn.update()
    if head.xcor()>290 or head.xcor()<-290 or head.ycor()>290 or head.ycor()<-290:
        time.sleep(1)
        head.goto(0,0)
        head.directoin = "stop"
        for segment in segments:
            segment.goto(1000,1000)
        segments.clear()
        score = 0
        delay = 0.1
        pen.clear()

Then continue so:

    if head.distance(food)<20:
        x = random.ranint(-290, 290)
        y = random.ranint(-290, 290)
        food.goto(x,y)
        new_segment = turtle.Turtle()
        new_segment.speed(0)
        new_segment.shape("square")
        new_segment.color("black", "darkgreen")
        new_segment.penup()
        segments.append(new_segment)
        score += 10
        
        if score > high_score:
            high_score = score
        pen.clear()
        pen.write("Score: {}  High Score: {}".format(score, high_score), align="center", font=("Courier", 24, "bold"))
    for index in range(len(segments)-1, 0, -1):
        x = segments[index-1].xcor()
        y = segments[index-1].ycor()
        segments[index].goto(x, y)

and finish like so:

    for index in range(len(segments)-1, 0, -1):
        x = segments[index-1].xcor()
        y = segments[index-1].ycor()
        segments[index].goto(x, y)
