1073. 多选题常见计分法(20)——python

刚开始写的那个逻辑有点混乱，只通过了三个测试点，所以今天索性又重新写了一个，这次更加的注重逻辑的实现，主要的就是使用了两个字典，一个是dir_count_wrong，用来保存每个题错误选项的次数，还有一个就是dir_list_wrong，是用来保存每个题的错误选项。
（1）首先是对正确选项以及同学的答案进行处理，放到字典中；
（2）对每一个同学的选择题进行分析，分为三种情况，全对，部分对以及答案错误，并且算出该同学的得分；
（3）在将同学的答题情况分为三种后，就可以分别进行统计， 全对时不用考虑，然后就是考虑部分对以及答案错误的情况；
（4）对每个同学的每个选项进行分析，若是错误的（这个错误包括漏选以及多选），则将该题的选项保存到该题的dir_list_wrong字典中，这个字典中的值就是错误选项的list，主要的作用就是判断该题的该选项是否是第一次出错；然后再根据是否是第一次出错，对保存选项次数的dir_count_wrong进行操作；
（5）之后就是统计出错的最多的选项，然后输出相应的格式。def get_input(M, dir_right_answers, list_grades):
#得到所有标准答案并存放在字典中, 并返回分数list
