一、画笔

　　在画布上，默认画布中心为坐标原点，且隐藏着一个直角坐标系，小海龟的初始正方向规定为X轴的正方向。使用小海龟绘图时，确定方向与距离进行绘制图像。

1.画笔自身属性

命令 说明
turtle.pensize() 设置画笔的宽度
turtle.pencolor() 设置画笔的颜色，可以使用“black”“red”或者RGB3元组
turtle.speed() 设置画笔的移动速度，参数的范围在[0,10]之间的整数，数字越大，速度越快

2.画笔运动属性

命令 说明
turtle.forward(distance) 向当前画笔方向移动distance像素长
turtle.backward(distance) 向当前画笔相反方向移动distance像素长度
turtle.right(degree) 顺时针移动degree°
turtle.left(degree) 逆时针移动degree°
turtle.pendown() 移动时绘制图形,缺省时也为绘制
turtle.goto(x,y) 将画笔移动到坐标为x,y的位置
turtle.penup() 移动时不绘制图形,提起笔，用于另起一个地方绘制时用
turtle.speed(speed) 画笔绘制的速度范围[0,10]整数
turtle.circle() 画圆,半径为正(负),表示圆心在画笔的左边(右边)画圆

3.画笔的控制命令

命令 说明
turtle.pensize(width) 绘制图形时的宽度
turtle.pencolor() 画笔颜色
turtle.fillcolor(colorstring) 绘制图形的填充颜色
turtle.color(color1, color2) 同时设置pencolor=color1, fillcolor=color2
turtle.filling() 返回当前是否在填充状态
turtle.begin_fill() 准备开始填充图形
turtle.end_fill() 填充完成；
turtle.hideturtle() 隐藏箭头显示；
turtle.showturtle() 与hideturtle()函数对应

4.其他操作：

turtle.hideturtle()   # 隐藏小海龟画笔
turtle.mainloop()     # 保留最后图像

二、图像展示

1.Mercedes LOGO

       

　　　　奔驰标志 1.0

        

　　　　奔驰标志 2.0

 

 

                  奔驰标志 3.0

附 3.0版本代码如下：

import turtle as t
import time
R = 150
r = R - 10

t.pensize(10)
t.color("black","white")
t.speed(10)
t.circle(R,360) # 画圆圈
t.penup()
t.left(90)
t.forward(R)
t.pensize(1)
t.pendown()
t.forward(R)
t.pensize(1)
t.fillcolor("black")
# 左侧三角形
t.begin_fill()
t.left(170)
t.forward(r)
