修改文件名
每次面对一大堆的文件要修改文件名的时候都会和头疼，明明都要求好了，却还是有人不按照规则命名。
所以！！！
import os
import re
p_Url = '文件夹的路径'
realColumn = '班级+姓名+学号'
#班级学号等等各种命名方式，用‘+’链接，一定要用‘+’（其他规则的没有写）
delimiter = '-'#指定分割符，如：会计-张三-333333-第一次作业（注意这里用的是‘-’，链接，如果将‘-’改为‘+’，那么就会用‘+’链接）
'''
查看谁没交
'''
id_list = []
name_list = []
stMap = {}
RL = []
idLong = 0
AllPeople = 0

最后，补充一点Students.txt的文件是必须的，因为必须要有人员与编号之间的对应关系。
如果其中有错误，请大家指正。
