turtle模块
turtle模块:python内置的绘图工具
turtle(海龟)模块,我们是用它来进行画图的,基本上就是画简单的直线,点,和曲线。
你可以把它想成一个小海龟,在沙滩上行走,然后留下的各种痕迹,使用Turtle模块可以绘制很多精美的图形。
基本操作(Turtle方法)
- turtle.forward(step):前进step个像素
- turtle.back(step):后退step个像素
- turtle.right():右转一个角度
- turtle.left():左转一个角度
- turtle.pencolor(“string”):画笔颜色
- turtle.fillcolor(“string”):填充颜色
- turtle.speed(int):运动速度
其他的turtle方法可以参见python官网
