用python画星空是怎样的呢？下面就让我们一起来了解一下吧：
在绘制星空的过程中一般需要运用到turtle工具，它是属于Python的标准库，当然也可以将其称之为海龟库，它能够用于描绘绘图的轨迹，并且操作也比较简单、便捷。
参考范例：
用python画星空的源代码介绍如下：
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()
