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)

end_fill()

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。。。

用python matplotlib画笛卡尔的心形线
import numpy as npimport numpy as np
import pylab as plt
from matplotlib import colors
a = [[] for i in range(1000)]
i = 0
while i j = 0
while j x = -1.8 + 0.003*i
y = -1.4 + 0.0028*j
z = y**2 + (-x - (y**2)**0.33333)**2
if z a[i].append(0.9)
else:
a[i].append(0.0)
j = j + 1
i = i + 1
cmap = colors.listedcolormap(['white', 'pink'])
im = plt.imshow(a, cmap = cmap, interpolation=bicubic )
plt.show()
