最近在Coursera上课。 台湾的课程：用Python做商管程式设计（一）(Programming for Business Computing in Python (1))。想说最近写程序很夯，挑战看看
没有专门下载Python，只是在colab.research.google.com/直接写了（用大姐的电脑）
目前才上到week 3的课程。 虽然课堂上老师讲的东西，看似简单，容易明白。等到自己要亲自动手写，从无到有，要做功课和作业时，才头痛。
想在这里记录一下 Week 3 做的作业。题目在这里就不多提了。主要就是想说--可能其实有更简单的方法写，只是身为一个程序小白，刚刚学会 assignment =, comparison ==, if, else, else if, nested if else...
我只会用最直白的方式写出来。这题的output有63种组合，我就傻傻的一个一个的写...... 写了200多行。（不重要的题外话：问题要的是“，”， 我写了“：”）虽然答题还是可以的，但假如是在真的考场有时间上的压力的话，做了这题就别想做其他题目了，已经耗尽了全部能量和精力。
