最近看到不少关于李峋同款爱心的视频、文章，今天我们也分享一下李峋同款爱心 Python 代码版。

简单来说李峋同款爱心就是一个动态的♥型效果，主要 Python 代码实现如下：

def __init__(self, generate_frame=20):# 原始爱心坐标集合self._points = set()  # 边缘扩散效果点坐标集合self._edge_diffusion_points = set()  # 中心扩散效果点坐标集合self._center_diffusion_points = set()  # 每帧动态点坐标self.all_points = {}  self.build(2000)self.random_halo = 1000self.generate_frame = generate_framefor frame in range(generate_frame): self.calc(frame)def build(self, number):for _ in range(number): t = random.unifORM(0, 2 * pi) x, y = heart(t) self._points.add((x, y))# 爱心内扩散for _x, _y in list(self._points): for _ in range(3):  x, y = scatter_inside(_x, _y, 0.05)  self._edge_diffusion_points.add((x, y))# 爱心内再次扩散point_list = list(self._points)for _ in range(4000): x, y = random.choice(point_list) x, y = scatter_inside(x, y, 0.17) self._center_diffusion_points.add((x, y))@staticmethodstaticmethoddef calc_position(x, y, ratio):force = 1 / (((x - X) ** 2 +     (y - Y) ** 2) ** 0.520)dx = ratio * force * (x - X) + random.randint(-1, 1)dy = ratio * force * (y - Y) + random.randint(-1, 1)return x - dx, y - dydef calc(self, generate_frame):ratio = 10 * curve(generate_frame / 10 * pi)halo_radius = int(4 + 6 * (1 + curve(generate_frame / 10 * pi)))halo_number = int( 3000 + 4000 * abs(curve(generate_frame / 10 * pi) ** 2))all_points = []# 光环heart_halo_point = set()for _ in range(halo_number): t = random.uniform(0, 2 * pi) x, y = heart(t, shrink_ratio=11.6) x, y = shrink(x, y, halo_radius) if (x, y) not in heart_halo_point:  heart_halo_point.add((x, y))  x += random.randint(-14, 14)  y += random.randint(-14, 14)  size = random.choice((1, 2, 2))  all_points.append((x, y, size))# 轮廓for x, y in self._points: x, y = self.calc_position(x, y, ratio) size = random.randint(1, 3) all_points.append((x, y, size))# 内容for x, y in self._edge_diffusion_points: x, y = self.calc_position(x, y, ratio) size = random.randint(1, 2) all_points.append((x, y, size))self.all_points[generate_frame] = all_pointsfor x, y in self._center_diffusion_points: x, y = self.calc_position(x, y, ratio) size = random.randint(1, 2) all_points.append((x, y, size))self.all_points[generate_frame] = all_points

实现效果如下：
