正值春節+情人節，用python畫一顆動態彩虹心加上祝福語

import matplotlib.pyplot as plt
import numpy as np
import math

Reds = plt.cm.Reds
Oranges = plt.cm.Oranges
spring = plt.cm.spring
Greens = plt.cm.Greens
winter = plt.cm.winter
Blues = plt.cm.Blues
BuPu = plt.cm.BuPu
num = [-0.3, -0.2, -0.1, 0, 0.1, 0.2, 0.3]
colors =
 
 [Reds, Oranges, spring, Greens, winter, Blues, BuPu]
text = ['love', 'health', 'goodness', 'success', 'beaty', 'rich', 'Happy']
x_local = [0, 1.2, -0.8, 0.8, 0.2, -0.4, 0]
y_local = [0, 0.2, -0.8, -0.6, 0.7, 0.4, 1.6]
time = [1, 1, 1, 1, 1, 1, 3]

for i in range(0, len(num)):
    t = np.linspace(0, math.pi, 1000)
    x =
 
 (1+num[i])*np.sin(t)
    y = np.cos(t) + np.power(x, 2.0 / 3)  # 心型曲線的引數方程 power引數說明：x1的x2次方

    plt.scatter(x, y, c=y, cmap=colors[i], s=40)
    plt.scatter(-x, y, c=y, cmap=colors[i], s=40)  # 漸變顏色曲線
    plt.axis([-2, 2, -2, 2])  # 座標軸範圍
    plt.text(x=x_local[i], y=y_local[i], s=text[i], ha='center'
 
, va='baseline',
             fontdict=dict(fontsize=14, color='r', family='monospace', weight='bold')) # 加文字祝福

    plt.axis('off')  # 隱藏座標軸
    plt.pause(time[i])
    plt.plot()

效果如下
