二级python——turtle绘制雪景艺术图
# SnowView.py
import turtle
import random
# -------绘制雪花---------------
def drawSnow():
turtle.hideturtle() # 隐藏画笔体现艺术效果
turtle.pensize(2) # 画笔大小
for i in range(100): # 100片雪花
# 雪花的RGB颜色参数，随机生成一个【0.0， 1.0）之间的数
r, g, b = random.random(), random.random(), random.random()
turtle.pencolor((r, g, b)) # 画笔颜色
turtle.penup() # 抬起画笔
turtle.setx(random.randint(-350, 350)) # 将x轴移动到指定位置
turtle.sety(random.randint(1, 270))
turtle.pendown() # 落笔
dens = random.randint(8, 12) # 花瓣数量
snowsize = random.randint(10, 14) # 雪花大小
for j in range(dens):
turtle.forward(snowsize)
turtle.backward(snowsize)
turtle.right(360/dens)
# ---------绘制雪地--------------------
def drawGround():
turtle.hideturtle()
for i in range(400):
turtle.pensize(random.randint(5, 10))
x = random.randint(-400, 350)
y = random.randint(-280, -1)
r, g, b = -y/280, -y/280, -y/280
turtle.pencolor((r, g, b))
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.forward(random.randint(40, 100))
# -------------------------------------------------
turtle.setup(800, 600, 200, 200) # 窗口大小
turtle.tracer(False)
turtle.bgcolor("black") # 窗口背景颜色
drawSnow()
drawGround()
turtle.done()
