Today, I will talk to you about how to use Python to help the school write a book management system. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

Not much to say, direct text began, saying just eat a meal is not a loss, is not a bonus did not give me!

Simple implementation of library management system

Classes and object-oriented programming

"Small clock library management system 1. Enquiry 2. increased by 3. Borrowing 4. Return 5. Exit """

class Book(object): def __init__(self,name,author,state,book_position): self.name = name self.author = author self.state = state #Judge book status 0: lent 1: not lent self.book_position = book_position #str (object) is automatically called when printing objects def __str__(self): return f"Title: {self.name}, Author: , Status: , Location: "def directory(self): self.start() while True: print("""Xiaozhong Library Management System: 1. Enquiry 2. increased by 3. Borrowing 4. Return 5. exit """) chioce = int(input(" Enter the action you want:")) if chioce == 1: name = input(" You want to query the title of the book: ") self.checkBook(name) elif chioce == 2: self.addBook() elif chioce == 3: self.BorrowBook() elif chioce == 4: self.return_book() elif chioce == 5: print(" Exit the system!

Please re-enter! ") book_Manag = Book_Manag() book_Manag.directory() After reading the above, do you have any further understanding of how to write a library management system for schools in Python?
