Mini-project # 2 - "Guess the number" game"
第三周的作业，大致就是两个给定的上下界，在其中随机一个数，让用的人输入猜的数字，告知他实际的数字比猜的大还是小，一共有[log(upper) / log(2)]次机会，策略是二分。
这次是带界面的，库是老师写的simplegui，在下面的链接里（科学上网）
现在完成了第一部分。输出还是在控制台而不是在画布。。
思路大致是这样：
用全局变量存上下界，通过按钮的动作给出。每次一开始调用newgame做各种预处理，随机出给定的数，计算剩余剩余猜的次数等等。每次按按钮也要记得调用newgame
打分的时候发现有人一开始没调用。。貌似是不行的吧？
接下来输入的时候获取输入值判断什么的。。次数没了要重新开始。
用了try防止不合法输入。。自己玩起来还没有什么问题。除了不太方便。。。。。= =
体会是：
python的全局变量。。。是要在函数里声明的。。
开发貌似很练码力。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
