>>> import turtle #导入turtle模块
>>> turtle.showturtle() #显示箭头
>>> turtle.write("高淇")
>>> turtle.forward(300)
>>> turtle.color("red")
>>> turtle.left(90) #左转箭头90度
>>> turtle.forward(300)#前进300像素
>>> turtle.goto(0,50) #去到坐标点（0，50）
>>> turtle.goto(0,0)
>>> turtle.penup()  #停止画线
>>> turtle.goto(0,300)
>>> turtle.pendown() #开始画线
>>> turtle.goto(100,200)
>>> turtle.circle(100) #半径是100
