用python画雪花飘落_python绘制雪景图

本文实例为大家分享了python绘制雪景图的具体代码，供大家参考，具体内容如下

绘制雪景图，应用到turtle和random。

from turtle import *

from random import *

# 绘制随机雪花

def DrawSnow(snow):

x = randrange(-750, 750)

y = randrange(-50, 400)

snowcolor = (randrange(0, 255), randrange(0, 255), randrange(0, 255))

snowsize = randrange(10, 20)

snowstyle = choice([30, 45])

snow.penup()

snow.setpos(x, y)

snow.pendown()

colormode(255)

snow.pencolor(snowcolor)

for i in range(int(360/snowstyle)):

if snowsize < 11:

snowstyle = 90

snow.forward(snowsize)

snow.backward(snowsize)

snow.right(snowstyle)

#绘制上半部分雪花

def InitSnow(n):

snow = Turtle()

for i in range(n):

DrawSnow(snow)

#绘制下半部分雪地

def InitField():

field = Turtle()

colormode(255)

for i in range(300):

x = randrange(-850, 850)

y = randrange(-400, 0)

width = randrange(50, 200)

length = randrange(3, 8)

field.penup()

field.setpos(x, y)

field.pendown()

tempcolor = int(-255 * y/400)

print(tempcolor)

fieldcolor = (tempcolor, tempcolor, tempcolor)

field.color(fieldcolor, fieldcolor)

field.begin_fill()

field.fd(width)

field.circle(length, 180)

field.fd(width)

field.circle(length, 180)

field.end_fill()

def main():

bgcolor("black")

tracer(False)

InitField()

InitSnow(200)

tracer(True)

mainloop()

if __name__ == '__main__':

main()
