前言

简介

💻 Python已经越来越来流行了,下面将通过这个文章详细介绍Python中的Turtle库（海龟库）

turtle绘图体系：1969年诞生，主要用于程序设计入门; turtle库是python的标准库之一；属于入门级的图形绘制函数库; 标准库：是随解释器直接安装到操作系统中的功能模块; 第三方库：需要经过安装才能使用的功能模块; 库：library、包package、模块module统称为模块; turtle库绘制原理：有一只海龟在窗体正中心，在画布上游走，走过的轨迹形成了绘制的图形，海龟由程序控制，可以自由改变颜色、方向宽度等;

Turtle 如何使用呢

💦 当然,我们想使用这个库需要先学习这个每个方法的意思是什么？

没有理论知识为实践做铺垫,是很难完成下面的题目

import turtle
turtle.speed("fastest")   #画笔速度（”快：fastest 慢的：slow”）
turtle.pensize(2) 	#画笔像素/宽度  
for i in range(100):	 #绘画100次
turtle.fd(2*i)        #前进；等价于forward(2*i)
turtle.left(90) 	#绘画矩形的一条边，逆时针移动
turtle.done()	#结束绘制

结果
