图书管理系统-python语言
简介:
这个题的原题是需要C++来写的,然后C++的完整代码我放在了这个博客:图书目录管理系统(C++),然后我用python在模拟一个过程的,没有完全按照题目来做,比较简单,后面补加一个链接了数据库的版本。
题目原型:
请设计一个简单的图书目录管理系统(初级版)。
图书目录信息包括:
统一书号(不超过13字符)
书名(不超过30字符)
作者(不超过20字符)
出版社(不超过30字符)
出版日期(包括:年、月、日)
价格(精确到分)
注意:为了保证运行窗口能正确地显示,请右击运行窗口,修改“属性”:
在“选项”选项卡中,选中“使用旧版本控制台”
在“字体”选项卡中,选择“8×16”“点阵字体”
在“布局”选项卡中,将屏幕窗口宽度均设为“120”。
具体需求如下:
显示如下的主菜单:
Append Find Remove Modify Show Quit > _
如果用户输入 A 或 a、F 或 f、R 或 r、M 或 m、S 或 s,则可完成相应的操作。如果用户输入其它字符,则显示错误信息。
程序将反复显示主菜单,让用户持续工作。如果用户输入 Q 或 q,则程序结束。
Append Find Remove Modify Show Quit > Q Thank you! Goodbye!
若用户输入其它字符,则显示错误信息。
Append Find Remove Modify Show Quit > B Incorrect choice! Append Find Remove Modify Show Quit > 9 Incorrect choice! Append Find Remove Modify Show Quit > + Incorrect choice!
若用户输入 A 或 a,则可以输入新书的信息,将其添加到图书目录中。
Append Find Remove Modify Show Quit > a ISBN: 9780439227148 Title: The Call of the Wild Author: Jack London Publisher: Scholastic Press Pub date: 2001/1/1 Price: 39.4 Append Find Remove Modify Show Quit > A ISBN: 9781772262902 Title: Oliver Twist Author: Charles Dickens Publisher: Engage Books Pub date: 2016/9/15 Price: 648 Append Find Remove Modify Show Quit > a ISBN: 9787515911076 Title: The Call of the Wild Author: Jack London Publisher: Aerospace Publishing House Pub date: 2016/5/1 Price: 29.8
若用户输入的日期信息不正确,则显示错误信息,并要求用户重新输入。
Append Find Remove Modify Show Quit > A ISBN: 9787501592401 Title: The Old Man and the Sea Author: Ernest Hemingway Publisher: Knowledge Press Pub date: 2016/2/30 Incorrect date! Please reenter: 2016/6/31 Incorrect date! Please reenter: 2016/8/1 Price: 25.8
若用户输入 S 或 s,则按书号升序排序,然后列表显示全部图书。
Append Find Remove Modify Show Quit > S ISBN--------- Title------------------------- Author-------------- Publisher--------------------- Pub-date-- Price--- 9780439227148 The Call of the Wild Jack London Scholastic Press 2001/01/01 39.40 9781772262902 Oliver Twist Charles Dickens Engage Books 2016/09/15 648.00 9787501592401 The Old Man and the Sea Ernest Hemingway Knowledge Press 2016/08/01 25.80 9787515911076 The Call of the Wild Jack London Aerospace Publishing House 2016/05/01 29.80
若用户输入 F 或 f,则输入书名,然后显示该书名的图书。如果没有对应的图书,则显示错误信息。
Append Find Remove Modify Show Quit > F Title: The Call of the Wild ISBN--------- Title------------------------- Author-------------- Publisher--------------------- Pub-date-- Price--- 9780439227148 The Call of the Wild Jack London Scholastic Press 2001/01/01 39.40 9787515911076 The Call of the Wild Jack London Aerospace Publishing House 2016/05/01 29.80 Append Find Remove Modify Show Quit > f Title: Gulliver's Travels Not found!
