Python学习第72天（复习：选课实现习题）

Posted 2020-12-15 崆峒山肖大侠

　　之前有一个关于选课的练习，一直没有给实现，趁着明天休息，琢磨一下给弄出来，本来以为今天能搞定，看来是我想多了。

　　先看一下文件分布吧

　　

 

 　　没啥可多说的，今天完成了一部分，剩下的明天搞定。

　　bin文件下：　　

import os,sys,logging,shelve
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASE_DIR)
from conf import setting
from core.main import Admin

if __name__ == \'__main__\':
    Admin.run()

　　conf文件下的setting　　

import os,time,shelve,sys
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASE_DIR)
from src.class_school import School
data_path = os.path.join(BASE_DIR+\'\\db\')
school_file =os.path.join(data_path,\'school\')

　　core文件下的main

import os,sys,logging,shelve
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASE_DIR)
from core.school_view import School_view
from core.teacher_view import Teacher_view
from coer.student_view import Student_view

class Admin:
    def run(self):
        exit_flag = False
        menu = u\'\'\'
        \\033[32;1m
        1.学生视图
        2.老师视图
        3.学校视图
        4.退出\\033[0m
        \'\'\'
        choice = {
            \'1\': Student_view ,
            \'2\': School_view ,
            \'3\': School_view ,
            \'4\': exit()
        }
        while not exit_flag:
            print(menu)
            user_option = input(\'请输入你想进入的界面>>>\')
            if user_option in choice:
                choice[user_option]()
            else:
                print(\'输入指令不正确！！！请重新输入！！！\')

　　关于logging模块、shelve模块，基本忘的差不多了，现在内容逐渐多了，复习貌似更重要，不能过于激进，争取端午节前实现自己的承诺。
