Python的图形绘制turtle库

turtle绘制小人

import turtle
turtle.setup(700,700,100,100)#setup()设置窗体大小，后两个参数可选，该函数也不是必须的
turtle.speed(10)#设置画笔移到速度，参数值为0-10，数字越大，速度越大

turtle.pensize(10)#设置画笔尺寸大小
turtle.pencolor('green')#设置画笔颜色
turtle.penup()#将画笔抬起（抬起时移到画笔将不会在画布留下痕迹）
turtle.goto(0,190)#将画笔移到（x,y）
turtle.pendown()#将画笔落下
turtle.circle(80,360)#画圆，半径为正表示圆心在画笔左边
turtle.fillcolor('yellow')

turtle.penup()
turtle.goto(-20,250)
turtle.seth(-90)#改变海龟行进方向，但不行进，属于绝对角度
turtle.pendown()
turtle.circle(20,180)

turtle.penup()
turtle.goto(-10,280)
turtle.pendown()
turtle.circle(20,180)

turtle.penup()
turtle.goto(50,280)
turtle.left(180)#tuetle.left() turtle.right() 可以改变海龟行进角度，属于相对角度，left逆时针移到角度，right顺时针移到角度
turtle.pendown()
turtle.circle(20,180)

turtle.penup()
turtle.goto(-25,195)
turtle.pendown()
turtle.fd(25)#画笔向前移到距离 
turtle.left(90)
turtle.fd(50)
turtle.left(90)
turtle.fd(25)
turtle.penup()
turtle.goto(-90,170)
turtle.left(180)
turtle.down()
for i in range(1,5):
    if i%2!=0:
        turtle.fd(200)
    else:
        turtle.fd(180)
    turtle.left(90)
for i in [-90,90]:
    turtle.penup()
    turtle.goto(i,120)
    if i==-90:
        turtle.right(90)
    else:
        turtle.left(180)
    turtle.down()
    turtle.fd(25)
    turtle.left(90)
    turtle.fd(180)
    turtle.right(90)
    turtle.circle(15)
turtle.penup()
turtle.goto(-60,-30)
turtle.right(90)
turtle.pendown()
turtle.fd(200)
turtle.left(90)
turtle.fd(25)


turtle.penup()
turtle.goto(60,-30)
turtle.right(90)
turtle.pendown()
turtle.fd(200)
turtle.right(90)
turtle.fd(25)

turtle.penup()
turtle.hideturtle()#隐藏画笔
#turtle.showturtle()#显示画笔
turtle.bk(100)#向后移到画笔
turtle.pencolor('red')
turtle.dot(100)#绘制一个半径为r的原点

结果如下
