用Python實現學生管理系統

這篇文章主要介紹“用Python實現學生管理系統”，在日常操作中，相信很多人在用Python實現學生管理系統問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”用Python實現學生管理系統”的疑惑有所幫助！接下來，請跟著小編一起來學習吧！

實現從面向過程到面向對象的過度，通過更改前面的學生管理系統實現面向對象，也證明了面向過程可以完美過度到面向對象，從而為以后的程序進步做了進一步優化，方便以后的程序更改。

完整代碼如下：

student_main模塊中的代碼

import student_tools


class Student(student_tools.StudentT):

    def __init__(self):
        self.user=['wangtaotao']
        self.pwd=['123456']
        student_tools.StudentT.__init__(self)

    #登錄
    def denglu(self):

        pwds = input("請輸入您的密碼:")
        if users in self.user and pwds in self.pwd:
            self.student()
        else:
            print("賬號或密碼不正確，請重新輸入")

    #注冊
    def zhuce(self):
        users=input("請輸入您要注冊的用戶名:")
        pwds=input("請輸入您要注冊的密碼:")
        self.user.append(users)
        self.pwd.append(pwds)
        print()
        print("注冊成功!")
