效果极佳:

简单总结一下好了,其实turtle库还是非常有用的,以后可以画张很有创意的图片去表白女神了,讲不好那天就用上了呢:

显示器和turtle窗体的左上角都是原点
turtle.setup(wIDth,height,startx,starty)设置窗体大小及位置,后面两个参数可选,非必需
空间坐标:绝对坐标:右方向x轴,上方向为y轴,正中心为原点,turtle.goto(x,y)让在任何位置的海龟到达指定的位置
海龟坐标:turtle.fd(d)海龟向前行多少像素
turtle.bk(d)向海龟的反方向运行
turtle.circle(r,angle)以海龟左边的某一点为圆心进行曲线运行
角度坐标:绝对角度:turtle.seth(angle)angle为绝对度数,表示改变海龟的运行方向
海龟角度:turtle.right(angle),turtle.left(angle)改变海龟的运行方向
RGB体系:turtle.colormode(mode)mode=1.0则改用0和1表示,mode=255则改用255和0表示,默认为小数
库引用:import <库名>,from <库名> import *或者from <库名> import <函数名>,import <库名> as <库别名>
画笔控制函数:turtle.penup()别名:turtle.pu()抬起画笔,turtle.pendown()别名:turtle.pd()落下画笔,turtle.pensize(wIDth)别名:turtle.wIDth(wIDth)设置画笔宽度,turtle.pencolor(color)设置画笔颜色,color有三种方式,颜色字符串,或者RGB小数值,或者RGB元组值,例如:turtle.pencolor((0.63,0.13,0.94))
运动控制函数:turtle.circle(r,angle),r(海龟左方向)表示半径,angle表示绘制的角度,默认是360度
方向控制函数:turtle.seth(angle)改变海龟的行进方向,顺时针转向
