图形化设计,导入turtle模块，import导入
turtle.showturtle()#显示箭头
turtle.write() #写字符
turtle.forward() #前行像素
turtle.color(`red`) #设置画笔颜色为红色
turtle.left(90) #箭头左转90度
turtle.forword(300) #再走300像素
turtle.goto(0,50) #去坐标(0,50)
turtle.goto(0,0) #去到相应坐标
turtle.penup() #抬笔，不画路径，
turtle.goto(0,300) #走300个像素，但是不画出路径
turtle.pendown() #放下画笔
turtle.circle(200) #画一个半径为200的圆
实践:利用turtle模块画奥运五环
#绘制奥运五环Python
import turtle
turtle.showturtle()
turtle.width(10)
turtle.color("blue")
turtle.circle(50)
turtle.penup()
turtle.forward(120)
turtle.pendown()
turtle.width(10)
turtle.color("black")
turtle.circle(50)
turtle.penup()
turtle.forward(120)
turtle.pendown()
turtle.width(10)
turtle.color("red")
turtle.circle(50)
turtle.penup()
turtle.goto(60,-50)
turtle.pendown()
turtle.width(10)
turtle.color("yellow")
turtle.circle(50)
turtle.penup()
turtle.goto(180,-50)
turtle.pendown()
turtle.width(10)
turtle.color("green")
turtle.circle(50)
turtle.done() #能使得打印完的图形定在显示页面
举一反三，按照这个思路，可以打印你想要的图形。赶快去给女朋友打印一个小心心吧！
