动态爱心python代码

以下是一个简单的动态爱心 Python 代码，它使用了 Tkinter 库中的 Canvas 控件来绘制图形界面，实现了一个动态的爱心效果：

import tkinter as tk
import math

class Heart:
    def __init__(self, canvas, x, y, size):
        self.canvas = canvas
        self.x = x
        self.y = y
        self.size = size
        self.draw()

    def draw(self):
        x = self.x
        y = self.y
        size = self.size
        self.shapes = []
        for i in range(200):
            t = i / math.pi
            x = 16 * math.sin(t) ** 3
            y = 13 * math.cos(t) - 5 * math.cos(2 * t) - 2 * math.cos(3 * t) - math.cos(4 * t)
            x = x * size + self.x
            y = y * size + self.y
            self.shapes.append(self.canvas.create_line(x, y, x + 1, y + 1, fill='red'))

    def move(self):
        for i in range(len(self.shapes)):
            t = i / math.pi
            x = 16 * math.sin(t) ** 3
            y = 13 * math.cos(t) - 5 * math.cos(2 * t) - 2 * math.cos(3 * t) - math.cos(4 * t)
            x = x * self.size + self.x
            y = y * self.size + self.y
            self.canvas.coords(self.shapes[i], x, y, x + 1, y + 1)

class App:
    def __init__(self, master):
        self.master = master
        self.canvas = tk.Canvas(master, width=400, height=400)
        self.canvas.pack()
        self.heart = Heart(self.canvas, 200, 200, 10)
        self.animate()

    def animate(self):
        self.heart.move()
        self.master.after(10, self.animate)

root = tk.Tk()
app = App(root)
root.mainloop()
