PatriotAct says:

It opens a new window and it looks fine, but it does not run and I just get Space Invaders (not responding) and it crashes. What did I do wrong? I know its not a complete code but I shouldn’t need to enter anymore for the screen to at least stay open. And note that I am not talking about how it originally closes immediately after opening, it stays open but just doesnt work.

import os
import turtle

wn = turtle.Screen()
wn.bgcolor(“black”)
wn.title(“Space Invaders”)

Dylan Loom says:

Hi there , I have copied the code exactly to how yours is on notepad++ I save the file. Then open it as I would in a normal document. And a screen opens for a second then closes. Should I be using a different ide or do I need any plugins etc

Pawel Charkiewicz says:

Tanush Shrivastava says:

whenever I try to run it off of my raspberry pi it says error syntax
this is my code

>>> import turtle
>>> import os
>>> wn = turtle.Screen()
>>> wn.bgcolor(“Black”)
>>> wn.title(“Space Invaders”)
>>> pen = turtle.Turtle()
>>> pen.color(“white”)
>>> pen.speed(0)
>>> pen.penup()
>>> pen.setposition(-300,-300)
>>> pen.pendown()
>>> for x in range(4):
pen.forward(600)
pen.lt(90)

>>> pen.hideturtle()
>>> character = turtle.Turtle()
>>> character.shape(“triangle”)
>>> character.speed(0)
>>> character.setposition(0,-250)
>>> character.setheading(90)
>>> character.color(“blue”)

Pengulous says:

If i put the border at -300,-300 then it is too big for the screen and all i see is the left and right sides of it anyone help?

kresna maheswara says:

hello chris how i learn python in package library

Cool Ice says:

Im using Jupyter and its running python 3 and the border_pen.penup() isnt working its having error??

WeirdButCoolGaming And Mapping says:

PS:For python 3 use input instead and dont use the delay otherwise the name would be Python Turtle Graphics

SlyFox says:

I’m getting back “This application has requested the Runtime to terminate it in an unusual way. ” when I try to make the screen. The window crashes immediately along with my kernel. I don’t know what to do here.

Tacticalswitch says:

The window that appears keeps crashing when I press “Run”. Says SPace Invaders and shows the turtle, just not responding.

ErNrGc says:

It always crash… why?! I am on Windows Pythn 3.6 (Solved)
The “”delay = input(“press enter to finish”)”” cause problems so put “turtle.mainloop()”.
(know that “raw_input” doesn’t work)

PD: Good vids :3

Le Grand Duelliste says:

Hi, I’m using python 3 but all it the screen and borders don’t stay on, they appear and disappear straight away.
Here’s the code, I copy pasted the exact one.

import turtle
import os

# Set up screen
wn = turtle.Screen()
wn.bgcolor(“black”)
wn.title(“Space Invaders”)

# Draw border
border_pen = turtle.Turtle()
border_pen.speed(0)
border_pen.color(“white”)
border_pen.penup()
border_pen.setposition(-300, -300)
border_pen.pendown()
border_pen.pensize(3)
for side in range(4):
border_pen.fd(600)
border_pen.lt(90)
border_pen.hideturtle()

# Create player turtle
player = turtle.Turtle()
player.color(“blue”)
player.shape(“triangle”)
player.penup()
player.speed(0)
player.setposition(0, -250)
player.setheading(90)

JRM Productions says:
