如何在Python idle中绘制一个带有乌龟图形的粘合剂？

import turtle

canvas = turtle.Screen()
pen = turtle.Turtle()

pen.shape("turtle")
pen.color("green")

# 绘制粘合剂的上部分
pen.penup()
pen.goto(0, 100)
pen.pendown()
pen.circle(50)

# 绘制粘合剂的下部分
pen.penup()
pen.goto(0, -100)
pen.pendown()
pen.circle(50)

canvas.exitonclick()

import turtle

canvas = turtle.Screen()
pen = turtle.Turtle()

pen.shape("turtle")
pen.color("green")

pen.penup()
pen.goto(0, 100)
pen.pendown()
pen.circle(50)

pen.penup()
pen.goto(0, -100)
pen.pendown()
pen.circle(50)

canvas.exitonclick()
