求问怎样用python/pythonturtle画“心”呢？

刚刚起步python，觉得python turtle真是萌神一般的存在呀～ 试着画了颗“心”，不过觉得方法实在是太笨了>

回复内容：

  from   turtle   import   * 
 def   curvemove  (): 
     for   i   in   range  (  200  ): 
         right  (  1  ) 
         forward  (  1  ) 
 color  (  'red'  ,  'pink'  )         
 begin_fill  () 
 left  (  140  ) 
 forward  (  111.65  ) 
 curvemove  () 
 left  (  120  ) 
 curvemove  () 
 forward  (  111.65  ) 
 end_fill  () 
 done  () 
  

from turtle import * from turtle import *
pensize(1)
color('black','red')
speed(2)
up()
goto(-12,100)
down()
begin_fill()
left(90)
circle(120,180)
circle(360,70.529)
left(38.942)
circle(360,70.529)
circle(120,180)
end_fill()
up()
goto(-250,-150)
down()

  from   pylab   import  * 
 t  =  linspace  (  0  ,  2  *  pi  ,  100  ) 
 x  =  sin  (  2  *  t  )   +   2  *  sin  (  t  ) 
 y  =-  cos  (  2  *  t  )  -  2  *  cos  (  t  ) 
 fill  (  x  ,  y  ,  'r'  ) 
 show  () 
  

心没画，玫瑰花倒是有一个 之前忘了帖代码，现在补上。 之前忘了帖代码，现在补上。
for i in range (1):
def paint(ang,r,ang2): #画图函数
turtle.penup()
turtle.setheading(ang)
turtle.pendown()
turtle.circle(r,ang2)


import turtle
turtle.speed(9)
turtle.color("white") #设置
turtle.pensize(7)
turtle.penup()
turtle.goto(50,-50)
turtle.pendown()
turtle.dot(200,"pink") #画背景
turtle.penup()
turtle.goto(50,86.6)
ang=-150
r=300
ang2=46
for j in range (21): #循环

paint(ang,r,ang2) #画弧
ang2-=25
paint(ang+ang2+25,r,-ang2) #回退
ang2+=25
ang+=66
r=r*0.9


思路大概就是：画圆弧，回退大约1/3，转向，减小半径，画圆弧......一直循环...

提醒我贴代码的那个小同学，我看了你资料，看来你和我一个学校而且选的同一个选修课呢。不过我这个作业交过了，所以你参考一下，不懂的可以问我。
照抄的话老师会打你屁屁的
(╯‵□′)╯︵┻━┻。35道哪个不会可以私信我。我给你思路~不过最近考试周，我不一定都能帮得上忙。。。
