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 ,from import *或者from import ,import as
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
