前言
太困了，索性写一个朴实无华的教程
介绍
功能
- 提取专业课程列表，以选择要生成的所有专业课
- 根据已选的专业课计算出每个学生的平均成绩，进行排序
- 英语快班成绩*1.1
- 对等级评定（优、良、中、及格）能够转换成分数（90、80、70、60）
- 只能根据单个专业原始成绩表生成该专业的成绩排名
- 生成的排名表含有各个课程的学分，方便用Excel进行人工核算
开发工具
使用python开发，主要使用xlrd、xlwt、tkinter等模块进行开发，代码简单，逻辑较清楚。
作者
一个名不见经传、心怀恪尽职守、疼爱助理（自己）的颇享受成就感的辅导员助理。
使用
用前须知
开发过程中处理的原始文件格式如下：
生成的成绩排名如下：
空白处的地方是该学生没有这门课程，在计算平均成绩时也不会算入
（可能的原因就是这门课是其他同学补修或重修来的，在选择课程时选中了它，而其他同学这门课程已经学过了。但该补修或重修同学的总成绩需要计入该课程）
开始使用
打开软件：
- 点击1处按钮，弹出对话框
- 在对话框选择原始excel文件，确认打开，完成第2步
- 点击3处按钮载入excel文件
- 在“选择要生成的科目”一栏中选择课程 公选课不计入成绩排名中，所以要筛选出必修课
- 在“选择英语快班所学的课程”一栏中选择快班学的大英课程 快班英语成绩要乘1.1
- 点击6处按钮，在同文件夹下生成专业成绩排名表，成功后会弹出成功对话框
代码
附上代码，希望给帮助到命中注定的人，如有问题可以联系博主哦！
