python；李峋同款跳动爱心代码

以下是李峋同款跳动爱心代码的Python实现：

import random
from math import sin, cos, pi, log
from tkinter import *

class Heart:
    def __init__(self, canvas, x, y, size):
        self.canvas = canvas
        self.x = x
        self.y = y
        self.size = size
        self.id = canvas.create_oval(x, y, x+size, y+size, fill='red', outline='')

    def jump(self):
        dx = random.randint(-10, 10)
        dy = random.randint(-10, 10)
        self.canvas.move(self.id, dx, dy)

    def beat(self):
        r = self.size / 2
        t = 0
        while True:
            x = self.x + r * 16 * sin(t)**3
            y = self.y - r * (13*cos(t) - 5*cos(2*t) - 2*cos(3*t) - cos(4*t))
            self.canvas.coords(self.id, x, y, x+self.size, y+self.size)
            t += pi / 16
            if t >= 2 * pi:
                t = 0
            self.canvas.update()

def main():
    root = Tk()
    root.title('Jumping Hearts')
    canvas = Canvas(root, width=500, height=500)
    canvas.pack()

    hearts = []
    for i in range(20):
        x = random.randint(50, 450)
        y = random.randint(50, 450)
        size = random.randint(20, 50)
        heart = Heart(canvas, x, y, size)
        hearts.append(heart)

    while True:
        for heart in hearts:
            heart.jump()
            heart.beat()

        canvas.update()
        canvas.after(50)

    root.mainloop()

if __name__ == '__main__':
    main()
