今天又到了圣诞节，大街小巷都响起了《Jingle Bells》,一路走来处处都装饰着圣诞树，浓浓的圣诞氛围~晚上刷公众号时偶然看到一篇用Python制作圣诞树的文章，果断敲起了代码.......
文章介绍了两种用Turtle库来制作圣诞树的方法，一是静态图二是动态图
方法一：
import turtle
screen = turtle.Screen()
screen.setup(800,600)
circle = turtle.Turtle()
circle.shape('circle')
circle.color('red')
circle.speed('fastest')
circle.up()
square = turtle.Turtle()
square.shape('square')
square.color('green')
square.speed('fastest')
square.up()
circle.goto(0,280)
circle.stamp()
k = 0
for i in range(1,17):
y = 30*i
for j in range(i-k):
x = 30*j
square.goto(x,-y+280)
square.stamp()
square.goto(-x, -y + 280)
square.stamp()
if i % 4 == 0:
x = 30 * (j+1)
circle.color('red')
circle.goto(-x, -y + 280)
circle.stamp()
circle.goto(x, -y + 280)
circle.stamp()
k += 2
if i % 4 == 3:
x = 30 * (j+1)
circle.color('yellow')
circle.goto(-x, -y + 280)
circle.stamp()
circle.goto(x, -y + 280)
circle.stamp()
square.color('brown')
for i in range(17,20):
y = 30 * i
for j in range(3):
x = 30 * j
square.goto(x, -y + 280)
square.stamp()
square.goto(-x, -y + 280)
square.stamp()
turtle.exitonclick()
运行后如下图

方法二：
import random
import time
n = 80.0
speed("fastest")
screensize(bg = 'seashell')
left(90)
forward(3*n)
color("orange","yellow")
begin_fill()
left(126)
for i in range(5):
forward(n/5)
right(144)
forward(n/5)
left(72)
end_fill()
right(126)
color("dark green")
backward(n*4.8)
def tree(d,s):
if d <= 0: return
forward(s)
tree(d-1,s*.8)
right(120)
tree(d-3,s*.5)
right(120)
tree(d - 3, s * .5)
right(120)
backward(s)
tree(15,n)
backward(n/2)
for i in range(200):
a = 200 - 400 * random.random()
b = 10 - 20 * random.random()
up()
forward(b)
left(90)
forward(a)
down()
if random.randint(0,1) == 0:
color('tomato')
else:
color('wheat')
circle(2)
up()
backward(a)
right(90)
backward(b)
time.sleep(60)
运行后如下

“世上当然有圣诞老人，我是，你也是。现在我们睡吧，想想最安静的事物，比如雪。雪正从星星上落下。”圣诞快乐，晚安。
