测开之路三十三：Flask实现扎金花游戏

访问http://localhost:8888/game随机获取一张扑克牌。
豹子（炸弹）：三张点相同的牌。例：AAA、222。
顺金（同花顺、色托）：花色相同的顺子。例：黑桃456、红桃789。最大的顺金为花色相同的JQK，最小的顺金为花色相同的123。
金花（色皮）：花色相同，非顺子。例：黑桃368，方块145。
顺子（拖拉机）：花色不同的顺子。例：黑桃5红桃6方块7。最大的顺子为花色不同的QKA，最小的顺子为花色不同的123。
对子：两张点数相同的牌。例：223，334。
单张：三张牌不组成任何类型的牌。

思路：
1、发牌
2、获取牌面花色和值
3、判断牌的性质，如：金花、顺子、对子···
4、对比双方的牌
5、返回状态：谁胜谁负，以及双方的牌
6、渲染到前端页面
