尽管海龟作图最初源自20世纪60年代的Logo编程语言[1],但一些很酷的Python程序员构建了一个库(library,库就是可以重用的代码的一个集合),来帮助其他程序员在Python中使用海龟作图。当我们输入了import turtle,就表示我们的程序能够使用那些Python程序员所编写的代码。图2-1中的小的黑色箭头表示海龟,它在屏幕上移动的...
Turtle库是Python语言中一个很流行的绘制图像的函数库,想象一个小乌龟,在一个横轴为x、纵轴为y的坐标系原点,(0,0)位置开始,它根据一组函数指令的控制,在这个平面坐标系中移动,从而在它爬行的路径上绘制了图形。 turtle绘图的基础知识: 一. 画布(canvas) 画布就是turtle为我们展开用于绘图区域,我们可以设置它的...

Some are tiny (e.g., many sphaerodactylid geckos) and others are huge (e.g., the anaconda and reticulate python). Most are terrestrial or arboreal, though many snakes are semiaquatic, spending much of their lives in or immediately adjacent to fresh water, or, less commonly, in estuaries...
