整理图书代码

# 图书整理系统代码设计 我可以帮你设计一个图书整理系统的代码框架。以下是基于Python的实现示例： ```python class Book: def __init__(self, title, author, isbn, category, location=None): self.title = title self.author = author self.isbn = isbn self.category = category self.location = location # 书架位置，如"A-12" self.is_borrowed = False def __str__(self): return f"{self.title} by {self.author} (ISBN: {self.isbn})" class Library: def __init__(self): self.books = [] def add_book(self, book): self.books.append(book) def remove_book(self, isbn): self.books = [book for book in self.books if book.isbn != isbn] def find_by_title(self, title): return [book for book in self.books if title.lower() in book.title.lower()] def find_by_author(self, author): return [book for book in self.books if author.lower() in book.author.lower()] def find_by_category(self, category): return [book for book in self.books if book.category.lower() == category.lower()] def borrow_book(self, isbn): for book in self.books: if book.isbn == isbn: if book.is_borrowed: return False book.is_borrowed = True return True return False def return_book(self, isbn): for book in self.books: if book.isbn == isbn and book.is_borrowed: book.is_borrowed = False return True return False def organize_by_category(self): organized = {} for book in self.books: if book.category not in organized: organized[book.category] = [] organized[book.category].append(book) return organized def assign_locations(self): categories = set(book.category for book in self.books) shelf = 1 for category in sorted(categories): books_in_category = self.find_by_category(category) for i, book in enumerate(books_in_category, 1): book.location = f"{category[0].upper()}-{shelf}-{i}" shelf += 1 # 使用示例 if __name__ == "__main__": library = Library() # 添加图书 library.add_book(Book("Python编程", "张三", "978-1-12345-678-0", "编程")) library.add_book(Book("算法导论", "李四", "978-2-23456-789-1", "算法")) library.add_book(Book("数据结构", "王五", "978-3-34567-890-2", "编程")) # 整理图书位置 library.assign_locations() # 按类别查找 programming_books = library.find_by_category("编程") for book in programming_books: print(f"{book} - 位置: {book.location}") # 借阅图书 library.borrow_book("978-1-12345-678-0") ``` ## 代码说明 1. `Book`类表示单本图书，包含、作者、ISBN、类别和位置信息 2. `Library`类管理图书集合，提供添加、删除、查找和整理功能 3. `assign_locations()`方法自动为图书分配书架位置，格式为"类别首字母-书架号-位置号" 4. 系统支持按、作者和类别查找图书 5. 包含简单的借阅和归还功能 ## 三条额外需要注意的逻辑点 1. 在实际应用中，ISBN应该进行有效性验证，确保符合国际标准书号的格式 2. 图书位置分配算法可以根据实际书架布局进行优化，考虑每层架子的容量限制 3. 需要添加持久化存储功能，将图书数据保存到数据库或文件中 [2025-05-20 09:47:52 | AI写代码神器 | 884点数解答]
