Why doesnt clear the body?

Python Help
1

Hi, i am working in snakegame with “turtle” library, but when i lost the body doesnt clear, i tried with segments.clear() and new_segments.clear(), but it didnt work.

Here is my code:

# import required modules
import turtle
import time
import random

delay = 0.1
score = 0
high_score = 0


# Creating a window screen
wn = turtle.Screen()
wn.title("🐍El juegardo🐍")
wn.bgcolor("black")
# the width and height can be put as user's choice
wn.setup(width=600, height=600)
wn.tracer(0)

# Snake head
head = turtle.Turtle()
head.speed(0)
head.shape("square")
head.color("white")
head.penup()
head.goto(0,0)
head.direction = "stop"


# food in the game
food = turtle.Turtle()
colors = random.choice(['white','green','lightblue'])
shapes = random.choice(['turtle'])
food.speed(0)
food.shape(shapes)
food.color(colors)
food.penup()
food.goto(0, 100)

pen = turtle.Turtle()
pen.speed(0)
pen.shape("square")
pen.color("white")
pen.penup()
pen.hideturtle()
pen.goto(0, 250)
pen.write("Score : 0 High Score : 0", align="center",
font=("candara", 24, "bold"))



# assigning key directions
def group():
    if head.direction != "down":
         head.direction = "up"


def godown():
    if head.direction != "up":
        head.direction = "down"


def goleft():
    if head.direction != "right":
        head.direction = "left"


def goright():
    if head.direction != "left":
        head.direction = "right"


def move():
    if head.direction == "up":
        y = head.ycor()
        head.sety(y+20)
    if head.direction == "down":
        y = head.ycor()
        head.sety(y-20)
    if head.direction == "left":
        x = head.xcor()
        head.setx(x-20)
    if head.direction == "right":
        x = head.xcor()
        head.setx(x+20)


        
wn.listen()
wn.onkeypress(group, "Up")
wn.onkeypress(godown, "Down")
wn.onkeypress(goleft, "Left")
wn.onkeypress(goright, "Right")

segments = []

# Main Gameplay
while True:
    wn.update()
    if head.xcor() > 290 or head.xcor() < -290 or head.ycor() > 290 or head.ycor() < -290:
       # pen.write("Score : {} High Score : {} ".format( score, high_score), align="center", font=("candara", 24, "bold"))
        time.sleep(1)
        head.goto(0, 0)
        head.direction = "Stop"
   
    if head.distance(food) < 20:
        x = random.randint(-270, 270)
        y = random.randint(-270, 270)
        food.goto(x, y)

        # Adding segment
        new_segment = turtle.Turtle()
        new_segment.speed(0)
        new_segment.shape("square")
        new_segment.color("white" if len(segments) % 2 else "red")
        new_segment.penup()
        segments.append(new_segment)
        delay -= 0.001
        score += 10
        if score > high_score:
            high_score = score
        pen.clear()
        pen.write("Score : {} High Score : {} ".format(
            score, high_score), align="center", font=("candara", 24, "bold"))
    # Checking for head collisions with body segments
    for index in range(len(segments)-1, 0, -1):
        x = segments[index-1].xcor()
        y = segments[index-1].ycor()
        segments[index].goto(x, y)
    if len(segments) > 0:
        x = head.xcor()
        y = head.ycor()
        segments[0].goto(x, y)
    move()
    for segment in segments:
        if segment.distance(head) < 20:
            time.sleep(1)
            head.goto(0, 0)
            head.direction = "stop"
            
            for segment in segments:
                segment.goto(1000, 1000)
                segments.clear()
                score = 0
                delay = 0.1
                pen.clear()
                pen.write("Perdiste :P".format(
                score), align="center", font=("candara", 24, "bold"))
                time.sleep(delay)


    time.sleep(delay)

Hi Lucas,

please use the button </> to format the code or enclose it manually between triple backticks (but do not confuse them with different characters):

```
# Your code will be here
```

Without that we (and you too) see it mangled.

Also please try to create a minimal code showing the problem. The whole code is a little bit long which makes it difficult for possible helpers. Alternatively explain which part of the code should perform the clearing.

I have never used a turtle object in Python, but here are some observations:

The segments.clear() statement is clearing the segment data object, but maybe the code needs an “undraw” somewhere, like a  for segment in segments:  loop to go through each segment and segment.undraw() it…?

Is this a ‘goup’ typo?

The bug is from a typo. The typo is clearing segments (the whole snake segments list) instead of each segment one at a time. This leaves the individual segments drawn on the screen

            for segment in segments:
                segment.goto(1000, 1000)
                segments.clear()

[Edit: ] You need to clear both segment and segments, apparently. When I changed segments -> segment, the snake’s body would clear from the screen at the beginning of the new game but the new game starts with the segments from the previous game.

[Edit: ] @LucasCapiz, this code has many areas that can be made more pythonic. If you would like to clean these up and learn about them, send me a direct Message. Doing it here would make too much off-topic traffic.
