以下是使用 Python 实现动态爱心的代码示例，该代码借助 `tkinter` 库创建窗口并绘制动态爱心图案： ```python import random from math import sin, cos, pi, log from tkinter import * CANVAS_WIDTH = 640 CANVAS_HEIGHT = 480 CANVAS_CENTER_X = CANVAS_WIDTH / 2 CANVAS_CENTER_Y = CANVAS_HEIGHT / 2 IMAGE_ENLARGE = 11 HEART_COLOR = "#FF69B4" def heart_function(t, shrink_ratio: float = IMAGE_ENLARGE): """ “爱心函数生成器” :param shrink_ratio: 放大比例 :param t: 参数 :return: 坐标 """ # 基础函数 x = 16 * (sin(t) ** 3) y = -(13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t)) # 放大 x *= shrink_ratio y *= shrink_ratio # 移到画布中央 x += CANVAS_CENTER_X y += CANVAS_CENTER_Y return int(x), int(y) def scatter_inside(x, y, beta=0.15): """ 随机内部扩散 :param x: 原 x :param y: 原 y :param beta: 强度 :return: 新坐标 """ ratio_x = - beta * log(random.random()) ratio_y = - beta * log(random.random()) dx = ratio_x * (x - CANVAS_CENTER_X) dy = ratio_y * (y - CANVAS_CENTER_Y) return x - dx, y - dy def shrink(x, y, ratio): """ 抖动 :param x: 原 x :param y: 原 y :param ratio: 比例 :return: 新坐标 """ force = -1 / (((x - CANVAS_CENTER_X) ** 2 + (y - CANVAS_CENTER_Y) ** 2) ** 0.6) # 这个参数... dx = ratio * force * (x - CANVAS_CENTER_X) dy = ratio * force * (y - CANVAS_CENTER_Y) return x - dx, y - dy def heart_positions(count, shrink_ratio: float = IMAGE_ENLARGE): """ 生成爱心的位置 :param count: 数量 :param shrink_ratio: 放大比例 :return: 坐标 """ positions = [] for _ in range(count): t = random.uniform(0, 2 * pi) # 随机不到的地方造成爱心有缺口 x, y = heart_function(t, shrink_ratio) positions.append((x, y)) return positions def random_color(): """ 随机颜色 :return: 颜色 """ colors = ['#FF69B4', '#FF1493', '#FFB6C1', '#FFC0CB'] return random.choice(colors) def draw(main, render_canvas, render_heart, render_frame=0): """ 绘制爱心 :param main: 窗口 :param render_canvas: 画布 :param render_heart: 爱心 :param render_frame: 帧 """ if render_frame % 10 == 0: # 每10帧改变一次颜色 HEART_COLOR = random_color() render_canvas.delete('all') new_heart = [] for x, y in render_heart: x, y = shrink(x, y, 0.05) new_heart.append((x, y)) for x, y in new_heart: render_canvas.create_rectangle(x, y, x + 1, y + 1, width=0, fill=HEART_COLOR) main.after(10, draw, main, render_canvas, new_heart, render_frame + 1) if __name__ == '__main__': root = Tk() canvas = Canvas(root, bg='black', height=CANVAS_HEIGHT, width=CANVAS_WIDTH) canvas.pack() heart = heart_positions(1000) draw(root, canvas, heart) root.mainloop() ``` 这段代码实现了动态爱心的效果，在窗口中会不断变化颜色和形状展示爱心。 ###
