python画跳动的爱心代码

以下是一个用Python画跳动的爱心的代码示例：

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

CANVAS_WIDTH = 800
CANVAS_HEIGHT = 600
CANVAS_CENTER_X = CANVAS_WIDTH // 2
CANVAS_CENTER_Y = CANVAS_HEIGHT // 2

class Heart:
    def __init__(self):
        self.color = "#ff8181"  # 心的颜色，这里使用了粉色
        self.shrink_ratio = 1.5  # 放大比例

    def render(self, canvas, frame):
        t = frame / 100  # 参数t，控制心的形状
        x = 16 * (sin(t) ** 3)
        y = -(13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t))
        x *= self.shrink_ratio
        y *= self.shrink_ratio
        x, y = self.scatter_inside(x, y)  # 随机内部扩散
        canvas.create_oval(CANVAS_CENTER_X + x - 2, CANVAS_CENTER_Y + y - 2,
                           CANVAS_CENTER_X + x + 2, CANVAS_CENTER_Y + y + 2,
                           fill=self.color)  # 在画布上绘制一个小圆点

    def scatter_inside(self, x, y, beta=0.15):
        ratio_x = - beta * log(random())
        ratio_y = - beta * log(random())
        dx = ratio_x * (x - CANVAS_CENTER_X)
        dy = ratio_y * (y - CANVAS_CENTER_Y)
        return x - dx, y - dy

def draw(main, render_canvas, render_heart, render_frame=0):
    render_canvas.delete('all')
    render_heart.render(render_canvas, render_frame)
    main.after(160, draw, main, render_canvas, render_heart, render_frame + 1)

if __name__ == '__main__':
    root = Tk()
    canvas = Canvas(root, bg='black', height=CANVAS_HEIGHT, width=CANVAS_WIDTH)
    canvas.pack()
    heart = Heart()
    draw(root, canvas, heart)
    root.mainloop()

这段代码使用了Tkinter库来创建一个窗口，并在窗口中绘制一个跳动的爱心。通过调整参数t的值，可以控制爱心的形状。同时，还使用了随机内部扩散的方法，使爱心在画布上有轻微的抖动效果。
