Today, let's use Python to make a starry sky.

---

1. Simulated starry sky

1,. First import the required library:

from turtle import *
from random import random, randint

2. Initial screen:

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()

 Total code:

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() < -width/2:
            star.hideturtle()
            star.setx(width/2 + randint(1, width))
            star.sety(randint(-height/2, height/2))
            star.showturtle()
