'''
Environment: Python3.6.4 to
write "Student Management System" (improved version), the initial requirements are as follows: You
must use custom functions to complete the modularization of the program
Student confidence at least includes: name, age, student number, other than this can be appropriately added
Functions that must be completed: add, delete, modify, query, traverse, exit
