一、前言

作为一个真ikun，这第一篇文章当然要写我们最帅的坤坤啦，哈哈哈~~~

先来看看效果图：

左边网上找的原图，右边是python turtle绘制的图形

 程序中的数据都是我在ppt中用绘图标尺量出来的，各块颜色也是用取色器取的，基本是高度还原图像了

 二、源码

然后下面是源码，将近180行：

import turtle as t
import math

t.setup(1000, 750)
t.setworldcoordinates(-800,-600,800,600)
t.title('I am ikun!!')
t.width(8)
t.speed(0)
t.pencolor('black')

    t.penup()
    t.setheading(0)
    t.goto(c_x,c_y-rad)
    t.pendown()

    if color is not None:
        t.end_fill()
