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()
