简易图书信息管理系统代码

简易图书信息管理系统的代码通常是一个简单的应用程序，用于存储和操作图书的数据，包括书名、作者、出版社、出版年份、ISBN号等。这个系统可能使用命令行界面或图形用户界面，下面是基于Python的一个简单示例，使用字典列表来模拟数据库：

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

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

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

    def search_by_title(self, title):
        return [book for book in self.books if book.title == title]

    def search_by_author(self, author):
        return [book for book in self.books if book.author == author]

# 使用示例
library = Library()
book1 = Book("Python编程：从入门到实践", "Eric Matthes", "O'Reilly Media", 2016, "978-1491957663")
book2 = Book("C++ Primer", "Lippman, Lajoie, and Moo", "Sams Publishing", 2013, "978-0321714113")

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

# 搜索书籍
search_results = library.search_by_title("Python编程")
for result in search_results:
    print(result.title)
