nump绘制爱心

 一：爱心函数

F(x)=x^2/3 + 0.9*(3.3-x²)^1/2*sin(love * x * π)

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


def plot_love(numbers):
    for k in range(numbers):
        time.sleep(0.05)

        def f(x, love=50):
            # y表示生成爱心的函数

            # love 控制爱心的形状

            y = x ** (2 / 3) + 0.9 * np.sqrt(3.3 - x ** 2) * np.sin(love * np.pi * x)


            return y

        x = np.linspace(0, 2, 1500)   # x 轴

        y = [f(i, k) for i in x]      # 调用上述函数 生成y轴


        plt.plot(x, y, color='red', linewidth=5)
        plt.plot(-x, y, color='red', linewidth=5)
        plt.xlim(-2, 2)

        plt.show()


plot_love(100)
