用Python画雪景图

        新年来临之际，用Python画了一幅雪景图，祝大家新年快乐，瑞雪兆丰年。

       

        说明：以下代码是从Python教程中学习来的。

#SnowView.py
from turtle import *
from random import *
def drawSnow():
    hideturtle()
    pensize(2)
    for i in range(100):
        r,g,b=random(),random(),random()
        pencolor(r,g,b)
        penup()
        setx(randint(-350,350))
        sety(randint(1,270))
        pendown()
        dens=randint(8,12)
        snowsize=randint(10,14)
        for j in range(dens):
            forward(snowsize)
            backward(snowsize)
            right(360/dens)

def drawGround():
    hideturtle()
    for i in range(400):
        pensize(randint(5,10))
        x=randint(-400,350)
        y=randint(-280,-1)
        r,g,b=-y/280,-y/280,-y/280
        pencolor((r,g,b))
        penup()
        goto(x,y)
        pendown()
        forward(randint(0,100))

setup(800,600,200,200)
tracer(False)
bgcolor("black")
drawSnow()
drawGround()
done()
