Python implementation of a simple student information management system

In this article, we share examples of Python implementation of the specific code of the student information management system for your reference, the details are as follows

Request a description:

Student information includes: student number, name, age, gender, date of birth, address, phone number, E-mail and so on. Try to design a student information management system that provides the following basic functions:

The system works in menu mode
Student information entry function (student information is saved in a file) --- Input
Student Information Viewing Function --- Output
Queries, sorting functions -- algorithms

1. Search by student number
2. Search by name

Deletion and modification of student information (optional)

The basic idea with the previously written piece of the book lending system, will not repeat here.

Directly on the code, the code is as follows:

import os
 
class Student(object):
    def __init__(self, sid, name, age=None, gender=None,
                 birth=None, address=None, tel=None, mail=None):
         = sid
         = name
         = age
         = gender
         = birth
         = address
         = tel
         = mail
 
    def __str__(self):
        return "%s：%s：%s：%s：%s：%s：%s：%s" %(, , , ,
                                    , , , )
 
class StudentManage(object):
    students = []
    def __init__(self):

        if (filename):
            with open(filename) as f:
                for line in f:
                    info = (':')
                    studentObj = Student(*info)
                    (studentObj)
            print("Loading cached student information was successful.")
        else:
            print("Uncached student information!")
 
    def add(self):
        sid = input("School number: ")
        name = input("Name: ")
        age = input("Age: ")
        gender = input("Sex (1-male 2-female):")
        birth = input("Date of birth (dd/mm/yyyy): ")
        address = input("Address: ")
        tel = input("Contact number: ")
        mail = input("E-mail: ")
        stu = Student(sid, name, age, gender, birth, address, tel, mail)
        (stu)
        print("Entry of student [%s] information was successful." %(name))
 
    def show(self):
        print("Student Information Display".center(50, '*'))
        for student in :
            print('-' * 50)
            print(str(student))

        # Sort by specified key value
        sorted_students = sorted(, key=lambda x: int(getattr(x, key)) if x else None)
        for student in sorted_students:
            print(student)
 
    def delete(self, key, value):
        if key in ['sid', 'name']:
            for student in :
                if getattr(student, key) == value:
                    (student)
                    print("Delete student information with attribute value [%s] of [%s]" % (key, value))
            else:
                print("No eligible student information found!")
        else:

Once run, the available function menu keys are output as follows:
