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

运行结果:
二.蓝色动态爱心
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')
