用python画星空源代码是什么？

用python画星空源代码是from turtle import *

from random import random,randint

screen = Screen()

width ,height = 800,600

screen.setup(width,height)

screen.title("模拟3D星空")

screen.bgcolor("black")

screen.mode("logo")

screen.delay(0)#这里要设为0，否则很卡

t = Turtle(visible = False,shape='circle')

t.pencolor("white")

t.fillcolor("white")

t.penup()

t.setheading(-90)

t.goto(width/2,randint(-height/2,height/2))

stars = []

for i in range(200):

star = t.clone()

s =random() /3

star.shapesize(s,s)

star.speed(int(s*10))

star.setx(width/2 + randint(1,width))

star.sety( randint(-height/2,height/2))

star.showturtle()

stars.append(star)

while True:

for star in stars:

star.setx(star.xcor() - 3 * star.speed())

if star.xcor()
