没区别啊,import的时候可以选择具体哪些类,如果import写了后面就不用写了,相当于是简写和全拼的区别

简介:turtle是一个简单的绘图工具。它提供了一个海龟,你可以把它理解为一个机器人,只听得懂有限的指令。 1.在文件头写上如下行,这能让我们在语句中插入中文 #-*- coding: utf-8 -*- 2.用import turtle导入turtle库 3.绘图窗口的原点(0,0)在...

画布(canvas) turtle.screensize(800, 600, "green") turtle.screensize() #返回默认大小(400, 300) 画笔控制命令: turtle.down() #移动时绘制图形,缺省时也为绘制 turtle.up() #移动时不绘制图形 turtle.pensize(width) #绘制图形时的宽度 turt...

turtle是python的简单的绘图模块,以下是一个例子 from turtle import * def yin(radius, color1, color2): width(3) color("black", color1) begin_fill() circle(radius/2., 180) circle(radius, 180) left(180) circle(-radius/2., 180) end_...
