python写图书管理系统

我可以回答这个问题。Python可以用于编写图书管理系统，可以使用Python的GUI库如Tkinter或PyQt来创建用户界面，使用Python的数据库模块如SQLite或MySQL来存储和管理图书信息。同时，Python也有许多第三方库可以用于处理Excel、PDF等格式的文件，方便图书管理。

好的，下面是一个简单的图书管理系统的Python代码：

class Book:
    def __init__(self, title, author, isbn, num_copies):
        self.title = title
        self.author = author
        self.isbn = isbn
        self.num_copies = num_copies

    def get_title(self):
        return self.title

    def get_author(self):
        return self.author

    def get_isbn(self):
        return self.isbn

    def get_num_copies(self):
        return self.num_copies

    def set_num_copies(self, num_copies):
        self.num_copies = num_copies


class Library:
    def __init__(self):
        self.books = []

    def add_book(self, book):
        self.books.append(book)

    def find_book(self, title):
        for book in self.books:
            if book.get_title() == title:
                return book
        return None

    def remove_book(self, book):
        self.books.remove(book)

    def display_books(self):
        for book in self.books:
            print("Title:", book.get_title())
            print("Author:", book.get_author())
            print("ISBN:", book.get_isbn())
            print("Number of Copies:", book.get_num_copies())
            print("")

    def borrow_book(self, title):
        book = self.find_book(title)
        if book is not None and book.get_num_copies() > 0:
            book.set_num_copies(book.get_num_copies() - 1)
            print("Book has been borrowed.")
        else:
            print("Book is not available.")

    def return_book(self, title):
        book = self.find_book(title)
        if book is not None:
            book.set_num_copies(book.get_num_copies() + 1)
            print("Book has been returned.")
        else:
            print("Book was not found.")

# Example usage:
library = Library()

book1 = Book("The Great Gatsby", "F. Scott Fitzgerald", "9780199536405", 5)
book2 = Book("To Kill a Mockingbird", "Harper Lee", "9780061120084", 3)
book3 = Book("The Catcher in the Rye", "J.D. Salinger", "9780316769488", 2)

library.add_book(book1)
library.add_book(book2)
library.add_book(book3)

library.display_books()

library.borrow_book("The Great Gatsby")
library.borrow_book("The Great Gatsby")
library.borrow_book("The Catcher in the Rye")

library.display_books()

library.return_book("The Great Gatsby")

library.display_books()

这个代码包含了两个类：`Book` 和 `Library`。`Book` 类表示一本书，包含书名、作者、ISBN 号以及库存数量。`Library` 类表示一个图书馆，包含了可以添加、查找、删除、显示和借阅书籍的方法。您可以根据需要添加其他的方法或者属性。

Python写图书管理系统的代码

我可以回答这个问题。以下是一个简单的Python图书管理系统的代码示例：

class Book:
    def __init__(self, title, author, isbn):
        self.title = title
        self.author = author
        self.isbn = isbn

class Library:
    def __init__(self):
        self.books = []

    def add_book(self, book):
        self.books.append(book)

    def remove_book(self, book):
        self.books.remove(book)

    def search_book(self, title):
        for book in self.books:
            if book.title == title:
                return book
        return None

    def display_books(self):
        for book in self.books:
            print(f"{book.title} by {book.author} (ISBN: {book.isbn})")

library = Library()
book1 = Book("The Great Gatsby", "F. Scott Fitzgerald", "978-0743273565")
book2 = Book("To Kill a Mockingbird", "Harper Lee", "978-0446310789")
book3 = Book("1984", "George Orwell", "978-0451524935")
library.add_book(book1)
library.add_book(book2)
library.add_book(book3)

library.display_books()

这个代码示例创建了两个类：`Book`和`Library`。`Book`类表示一本书，包含书的标题、作者和ISBN号。`Library`类表示一个图书馆，包含一个书籍列表，以及添加、删除、搜索和显示书籍的方法。在这个示例中，我们创建了一个`Library`实例，添加了三本书，并显示了所有书籍的信息。
