用Python给学弟准备追女神要用的多种流行的表白爱心代码【源码】
本文将介绍利用Python画多种不同的爱心形态，表白代码看这一篇文章就够啦，有感兴趣的朋友可以收藏起来。
1、三维爱心
效果图：
首先安装matplotlib
参考代码：
#!/usr/bin/env python3
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import cm
from matplotlib.ticker import LinearLocator, FormatStrFormatter
import matplotlib.pyplot as plt
import numpy as np
def heart_3d(x,y,z):
return (x**2+(9/4)*y**2+z**2-1)**3-x**2*z**3-(9/80)*y**2*z**3
def plot_implicit(fn, bbox=(-1.5, 1.5)):
''' create a plot of an implicit function
fn ...implicit function (plot where fn==0)
bbox ..the x,y,and z limits of plotted interval'''
xmin, xmax, ymin, ymax, zmin, zmax = bbox*3
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
A = np.linspace(xmin, xmax, 100) # resolution of the contour
B = np.linspace(xmin, xmax, 40) # number of slices
A1, A2 = np.meshgrid(A, A) # grid on which the contour is plotted
for z in B: # plot contours in the XY plane
X, Y = A1, A2
Z = fn(X, Y, z)
cset = ax.contour(X, Y, Z+z, [z], zdir='z', colors=('r',))
# [z] defines the only level to plot
# for this contour for this value of z
for y in B: # plot contours in the XZ plane
X, Z = A1, A2
Y = fn(X, y, Z)
cset = ax.contour(X, Y+y, Z, [y], zdir='y', colors=('red',))
for x in B: # plot contours in the YZ plane
Y, Z = A1, A2
X = fn(x, Y, Z)
cset = ax.contour(X+x, Y, Z, [x], zdir='x',colors=('red',))
# must set plot limits because the contour will likely extend
# way beyond the displayed level. Otherwise matplotlib extends the plot limits
# to encompass all values in the contour.
ax.set_zlim3d(zmin, zmax)
ax.set_xlim3d(xmin, xmax)
ax.set_ylim3d(ymin, ymax)
plt.show()
if __name__ == '__main__':
plot_implicit(heart_3d)
#!/usr/bin/env python3
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import cm
from matplotlib.ticker import LinearLocator, FormatStrFormatter
import matplotlib.pyplot as plt
import numpy as np
def heart_3d(x,y,z):
return (x**2+(9/4)*y**2+z**2-1)**3-x**2*z**3-(9/80)*y**2*z**3
def plot_implicit(fn, bbox=(-1.5, 1.5)):
''' create a plot of an implicit function
fn ...implicit function (plot where fn==0)
bbox ..the x,y,and z limits of plotted interval'''
xmin, xmax, ymin, ymax, zmin, zmax = bbox*3
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
A = np.linspace(xmin, xmax, 100) # resolution of the contour
B = np.linspace(xmin, xmax, 40) # number of slices
A1, A2 = np.meshgrid(A, A) # grid on which the contour is plotted
for z in B: # plot contours in the XY plane
X, Y = A1, A2
Z = fn(X, Y, z)
cset = ax.contour(X, Y, Z+z, [z], zdir='z', colors=('r',))
# [z] defines the only level to plot
# for this contour for this value of z
for y in B: # plot contours in the XZ plane
X, Z = A1, A2
Y = fn(X, y, Z)
cset = ax.contour(X, Y+y, Z, [y], zdir='y', colors=('red',))
for x in B: # plot contours in the YZ plane
Y, Z = A1, A2
X = fn(x, Y, Z)
cset = ax.contour(X+x, Y, Z, [x], zdir='x',colors=('red',))
# must set plot limits because the contour will likely extend
# way beyond the displayed level. Otherwise matplotlib extends the plot limits
# to encompass all values in the contour.
ax.set_zlim3d(zmin, zmax)
ax.set_xlim3d(xmin, xmax)
ax.set_ylim3d(ymin, ymax)
plt.show()
if __name__ == '__main__':
plot_implicit(heart_3d)
2、红色爱心
效果图：
参考代码：
import turtle
turtle.bgcolor("black")
turtle.pensize(2)
sizeh = 1.2
def curve():
for ii in range(200):
turtle.right(1)
turtle.forward(1 * sizeh)
turtle.speed(0)
turtle.color("red", "red")
turtle.begin_fill()
turtle.left(140)
turtle.forward(111.65 * sizeh)
curve()
turtle.left(120)
curve()
turtle.forward(111.65 * sizeh)
turtle.end_fill()
turtle.hideturtle()
3、Love字体爱心
效果图：
参考代码：
import time
words = input('请输出想要表达的文字:')
#例子：words = "Dear lili, Happy Valentine's Day! Lyon Will Always Love You Till The End! ♥ Forever! ♥"
for item in words.split():
#要想实现打印出字符间的空格效果，此处添加：item = item+' '
letterlist = []#letterlist是所有打印字符的总list，里面包含y条子列表list_X
for y in range(12, -12, -1):
list_X = []#list_X是X轴上的打印字符列表，里面装着一个String类的letters
letters = ''#letters即为list_X内的字符串，实际是本行要打印的所有字符
for x in range(-30, 30):#*是乘法，**是幂次方
expression = ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3
if expression <= 0:
letters += item[(x-y) % len(item)]
else:
letters += ' '
list_X.append(letters)
letterlist += list_X
print('\n'.join(letterlist))
time.sleep(1.5);
但是，有点太单调了点，来，将代码简单改造一下，实现动态输出心形的，代码如下：
import time
words = input('请输出想要表达的文字:')
for item in words.split():
print('\n'.join([''.join([(item[(x-y) % len(item)] if ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3 <= 0 else ' ') for x in range(-30, 30)]) for y in range(12, -12, -1)]))
time.sleep(1.5)
4、粉色桃心
效果图：
参考代码：
# -*- coding:utf-8 -*-
import turtle
import time
# 画爱心的顶部
def LittleHeart():
for i in range(200):
turtle.right(1)
turtle.forward(2)
# 输入表白的语句，默认I Love you
love = input('请输入表白语句，默认为输入为"I Love you": ')
# 输入署名或者赠谁，没有不执行
me = input('请输入您心上人的姓名或者昵称: ')
if love == '':
love = 'I Love you'
# 窗口大小
turtle.setup(width=800, height=500)
# 颜色
turtle.color('red', 'pink')
# 笔粗细
turtle.pensize(5)
# 速度
turtle.speed(1)
# 提笔
turtle.up()
# 隐藏笔
turtle.hideturtle()
# 去到的坐标,窗口中心为0,0
turtle.goto(0, -180)
turtle.showturtle()
# 画上线
turtle.down()
turtle.speed(1)
turtle.begin_fill()
turtle.left(140)
turtle.forward(224)
# 调用画爱心左边的顶部
LittleHeart()
# 调用画爱右边的顶部
turtle.left(120)
LittleHeart()
# 画下线
turtle.forward(224)
turtle.end_fill()
turtle.pensize(5)
turtle.up()
turtle.hideturtle()
# 在心中写字 一次
turtle.goto(0, 0)
turtle.showturtle()
turtle.color('#CD5C5C', 'pink')
# 在心中写字 font可以设置字体自己电脑有的都可以设 align开始写字的位置
turtle.write(love, font=('gungsuh', 30,), align="center")
turtle.up()
turtle.hideturtle()
time.sleep(2)
# 在心中写字 二次
turtle.goto(0, 0)
turtle.showturtle()
turtle.color('red', 'pink')
turtle.write(love, font=('gungsuh', 30,), align="center")
turtle.up()
turtle.hideturtle()
# 写署名
if me != '':
turtle.color('black', 'pink')
time.sleep(2)
turtle.goto(180, -180)
turtle.showturtle()
turtle.write(me, font=(20,), align="center", move=True)
# 点击窗口关闭
window = turtle.Screen()
window.exitonclick()
