我是靠谱客的博主背后小虾米，最近开发中收集的这篇文章主要介绍【Python】520爱她就用Python给她做一个漂亮的小心心，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

今天恰逢520，于是打算用Python画个❤
$（x^{2}）$

网上发现这个函数，该函数图像是一个爱心❤，刚好满足需要

$(x^{2}+y^{2}-1)^{3}-x^{2}y^{3} = 0$

开始制作

首先要有这两个包

import numpy as np
import matplotlib.pyplot as plt

接下来上代码

# -*- coding: utf-8 -*-
import numpy as np
import matplotlib.pyplot as plt
x_coords = np.linspace(- 100, 100, 500)
y_coords = np.linspace(- 100, 100, 500)
points = []
for y in y_coords:
for x in x_coords:
if ((x * 0.03) ** 2 + (y * 0.03) ** 2 - 1) ** 3 - (x * 0.03) ** 2 * (y * 0.03) ** 3 <= 0:
points.append({"x": x, "y": y})
heart_x = list(map(lambda point: point["x"], points))
heart_y = list(map(lambda point: point["y"], points))
plt.scatter(heart_x, heart_y, s= 10, alpha= 0.5, c=range(len(heart_x)), cmap="Greens_r")
# 其中最后一个参数cmap="XXX"可以换不同颜色的爱心
plt.show()

其中倒数第二行的cmap="XXX"里面可以换不同的爱心的颜色

一共有这么多种颜色的爱心：

可以拿去玩个够，哈哈哈哈哈哈哈哈哈哈

下面生成个爱心试一试
