用python画星空源代码

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()
