python/R 绘制圣诞树
圣诞节快到了，想着用python、r来画画圣诞树玩，就在网络上各种找方法，不喜勿喷哈~~
Python
1、

square.color('green')
square.speed('fastest')
square.up()

circle.stamp()

for i in range(1, 17):
y = 30*i
for j in range(i-k):

square.goto(x,-y+280)
square.stamp()

square.stamp()

turtle.exitonclick()
2、

3、

这个在使用python运行的时候，要用Python2，python3的话，颜色是不会变的。 嗯，最起码我是这样的。
