本次运用python的一个绘图库turtle，画了一朵玫瑰花，如果有一位可爱的小姐姐看到，那就送给你啦！效果如下：
源代码如下：
# 导入turtle库
import turtle
# 设置初始的位置
turtle.penup()
turtle.left(90)
turtle.fd(200)
turtle.pendown()
turtle.right(90)
# bud
turtle.fillcolor("red")
turtle.begin_fill()
turtle.circle(10,180)
turtle.circle(25,110)
turtle.left(50)
turtle.circle(60,45)
turtle.circle(20,170)
turtle.right(24)
turtle.fd(30)
turtle.left(10)
turtle.circle(30,110)
turtle.fd(20)
turtle.left(40)
turtle.circle(90,70)
turtle.circle(30,150)

turtle.circle(80,90)
turtle.left(15)
turtle.fd(45)
turtle.right(165)
turtle.fd(20)
turtle.left(155)
turtle.circle(150,80)

turtle.circle(150,90)
turtle.end_fill()
