Python资料网推荐使用Python绘制跳动的爱心，让你的代码也充满爱意！这篇文章给大家，欢迎收藏Python资料网享受知识的乐趣

今天我要分享一个浪漫小技巧，使用Python中的HTML制作一个立体、动态的小爱心。通过成千上百个小爱心的组合，形成一个大爱心，从内到外呈现出立体的效果，给人带来强烈的视觉冲击。这个小技巧非常浪漫，让人感受到爱的力量。

一．粉色爱心


</style>
  <body>
    <!-- 樱花 -->
    <div id="jsi-cherry-container" class="container">
      <audio autoplay="autopaly">
        <source src="renxi.mp3" type="audio/mp3" />
      </audio>
      <img class="img" src="./123.png" alt="" />
      <!-- 爱心 -->
      <canvas id="pinkboard" class="container"> </canvas>
    </div>

(function () {
      var b = 0;
      var c = ["ms", "moz", "webkit", "o"];
      for (var a = 0; a < c.length && !window.requestAnimationFrame; ++a) {
        window.requestAnimationFrame = window[c[a] + "RequestAnimationFrame"];
        window.cancelAnimationFrame =
          window[c[a] + "CancelAnimationFrame"] ||
          window[c[a] + "CancelRequestAnimationFrame"];
      }
      if (!window.requestAnimationFrame) {
        window.requestAnimationFrame = function (h, e) {
          var d = new Date().getTime();
          var f = Math.max(0, 16 - (d - b));
          var g = window.setTimeout(function () {
            h(d + f);
          }, f);
          b = d + f;
          return g;
        };
      }
      if (!window.cancelAnimationFrame) {
        window.cancelAnimationFrame = function (d) {
          clearTimeout(d);
        };
      }
    })();

    /*
     *Point class
     */
    var Point = (function () {
      function Point(x, y) {
        this.x = typeof x !== "undefined" ? x : 0;
        this.y = typeof y !== "undefined" ? y : 0;
      }
      Point.prototype.clone = function () {
        return new Point(this.x, this.y);
      };
      Point.prototype.length = function (length) {
        if (typeof length == "undefined")
          return Math.sqrt(this.x * this.x + this.y * this.y);
        this.normalize();
        this.x *= length;
        this.y *= length;
        return this;
      };
      Point.prototype.normalize = function () {
        var length = this.length();
        this.x /= length;
        this.y /= length;
        return this;
      };
      return Point;
    })();

    /*
     * Particle class
     */
    var Particle = (function () {
      function Particle() {
        this.position = new Point();
        this.velocity = new Point();
        this.acceleration = new Point();
        this.age = 0;
      }
      Particle.prototype.initialize = function (x, y, dx, dy) {
        this.position.x = x;
        this.position.y = y;
        this.velocity.x = dx;
        this.velocity.y = dy;
        this.acceleration.x = dx * settings.particles.effect;
        this.acceleration.y = dy * settings.particles.effect;
        this.age = 0;
      };
      Particle.prototype.update = function (deltaTime) {
        this.position.x += this.velocity.x * deltaTime;
        this.position.y += this.velocity.y * deltaTime;
        this.velocity.x += this.acceleration.x * deltaTime;
        this.velocity.y += this.acceleration.y * deltaTime;
        this.age += deltaTime;
      };
      Particle.prototype.draw = function (context, image) {
        function ease(t) {
          return --t * t * t + 1;
        }
        var size = image.width * ease(this.age / settings.particles.duration);
        context.globalAlpha = 1 - this.age / settings.particles.duration;
        context.drawImage(
          image,
          this.position.x - size / 2,
          this.position.y - size / 2,
          size,
          size
        );
      };
      return Particle;
    })();

运行结果：

二．蓝色动态爱心

表白界面

下边是表白运行代码：


def OK():            #同意按钮
    root.destroy()
    love()           #同意后显示漂浮爱心
def NO():            #拒绝按钮，拒绝不会退出，必须同意才可以退出哦~
    tk.messagebox.showwarning('❤','再给你一次机会！')
def closeWindow():
    tk.messagebox.showwarning('❤','逃避是没有用的哦')
