pyQt5之2048小游戏

什么是2048？

《2048》一款益智小游戏，游戏的规则十分简单，是时下一款简单易上手的数字小游戏
游戏规则：
游戏的规则很简单，你需要控制所有方块向同一个方向运动，两个相同数字方块撞在一起

之后合并成为他们的和，每次操作之后会随机生成一个2或者4，最终得到一个“2048”的方块就算胜利了

什么是pyQT5?

pyqt5是一套Python绑定Digia QT5应用的框架。它可用于Python 2和3。

pyqt5做为Python的一个模块，它有620多个类和6000个函数和方法。这是一个跨平台的工具包，

它可以运行在所有主要的操作系统，包括UNIX，Windows，Mac OS。pyqt5是双重许可。开发者可以在GPL和商业许可之间进行选择。
