前言
Python因其众多的第三方库而闻名，其中，用于绘制图形的turtle库由于其简单易用和方便性得到了广泛的青睐。笔者对此有些许兴趣，欲在后来的文章中对此展开学习，便先发布一篇预热文章，展现Python中使用turtle所能达到的效果如何。
内容概要
文章不会进行具体代码上的分析，只集结众家之长，主要展示的内容有：轮回绘制五角形、递归绘制Koch雪花曲线、画小人发射爱心、绘制皮卡丘、绘制魔法少女小圆晓美焰等。
分区展示
轮回绘制五角形
这是所有展示代码中最短的一个程序，仅有一个for循环就解决了问题，展现了turtle库便捷的功能，完整代码如下：
import turtle as t
t.color("red")
for i in range(270):
t.fd(i)
t.left(70)
t.done() 绘制效果如图：
递归绘制Koch雪花曲线
采取了递归的方法解决问题，27行，同样简练明了，完整代码如下：
import turtle
def koch(size, n):
if n == 0:
turtle.fd(size)
else:
for angle in [0, 60, -120, 60]:
turtle.left(angle)
koch(size/3, n-1)
def main():
turtle.setup(1200, 1000)
turtle.speed(11)
turtle.penup()
turtle.goto(-300, 200)
turtle.pendown()
turtle.pensize(2)
level = 4
koch(600, level) # 3阶科赫曲线
turtle.right(120)
koch(600, level)
turtle.right(120)
koch(600, level)
turtle.hideturtle()
turtle.done()
main() 绘制效果如图:
画小人发射爱心
开始出现曲线，但基本都是规则曲线，所以整体上难度并不高，完整代码如下：

小结
从上述的几个例子来看，能完成尤其是最后一个有很大难度的人物绘制，Python中的第三方库turtle还是很有实力的。但与此同时，我们也能看到即使是这样一个方便的库，在绘制高难度图形时还是需要编写者很大的耐心和打磨精神的。这也一定程度上启示编程路上不断前行的学习者们要有着不弃的精神，方能打磨出优秀的程序
