流星雨python代码

以下是Python实现流星雨的代码：

import turtle as tu
import random as ra
import math

tu.setup(1.0, 1.0)
tu.screensize(1.0, 1.0)
tu.bgcolor('black')

t = tu.Pen()
t.ht()

colors = ['red', 'yellow', 'white', 'purple', 'blue']

while True:
    x = ra.randint(-500, 500)
    y = ra.randint(200, 800)
    t.pu()
    t.goto(x, y)
    t.pd()
    t.pencolor(ra.choice(colors))
    size = ra.randint(10, 40)
    for i in range(size):
        t.fd(i)
        t.rt(144.0 - 360.0 / (2 * size))

    t.undo()
