python 基于控制台的学生管理系统

最近在学校python的时候想到以前学习的时候用java实现过类似的控制台的管理系统，现在学习python，我认为这也是认识语言的第一步。所以基于dict和list对学生信息管理做了一个简单的展示。

数据结构

学生数据 ={} 字典类型

json结构为

导入模块也使用此json结构，需要在文件目录自建data.txt

{
        "665000": {
            "name": "lisi",
            "gender": "女",
            "class": "aute",
            "graders": {
                "chinese": "12",
                "math": "44",
                "english": "54"
            }
        }
    }

这是主界面

对应了五个功能模块
下面展示部分功能
