利用Python实现图书馆管理系统代码

在Python中实现一个简单的图书馆管理系统可以包含借阅、归还图书以及查询库存等基本功能。这里提供一个简化的示例代码框架：

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

class Library:
    def __init__(self):
        self.books = {}

    def add_book(self, book_id, title, author):
        self.books[book_id] = Book(title, author)

    def borrow_book(self, book_id, borrower_name):
        if book_id not in self.books or self.books[book_id].is_borrowed:
            print("这本书已借出或不存在")
        else:
            self.books[book_id].is_borrowed = True
            print(f"{borrower_name}成功借走了{self.books[book_id].title}")

    def return_book(self, book_id):
        if book_id not in self.books or not self.books[book_id].is_borrowed:
            print("这本书未被借出或不存在")
        else:
            self.books[book_id].is_borrowed = False
            print(f"{book_id}已被归还")

    def search_books(self, keyword):
        results = [book for book in self.books.values() if keyword in book.title]
        if results:
            print("搜索结果:")
            for result in results:
                print(result.title)
        else:
            print("找不到匹配的书籍")

# 使用示例
library = Library()
library.add_book(1, "Python编程", "John Doe")
library.borrow_book(1, "Alice")
library.search_books("Doe")
library.return_book(1)

这个例子只是一个基础版本，实际应用中可能需要连接数据库存储书籍信息，添加用户认证机制，并处理并发控制等问题。
