Python 学生信息管理系统——文章中源码100%真实有效—–如何将类、初始化属性、模块、循环判断、静态方法等一系列知识点结合起来做一个项目

这篇博客主要就是把学生管理系统进行源码分享，这段源码很好的将前面所学的全部串在一起。就我个人而言真的是非常有价值。就算你python前面的基础不好，学完这个系统你会有重获新生的感觉。

本文适合需要用python完成课程大作业、python爱好者、python路上的学习者、初学python者、需要将python知识点串在一起的人、上进的人。

class Student(object): def __init__(self,name,gender,tell): self.name=name self.gender=gender self.tell=tell def __str__(self): return f"{self.name},{self.gender},{self.tell}"

student.py主要是初始化学生的初始化属性，包括名字（name）、性别（gender）、电话号码（tell）。方便上面manageSystem.py调用，使得代码更加简洁。

本文上传纯属是为了带大家分享，记录代码，方便以后查看

以上截图是文件所属目录，目录不对调用的时候是会报错的，所以要注意文件目录。
以上代码看懂我认为python基础就没什么问题了
