可以使用部分中文。这是一个简单的图书馆管理系统的示例代码。其中Book类表示一本书，Library类表示整个图书馆，包括添加和删除图书、查询图书信息以及借还书等功能。在主函数中创建了一个图书馆对象，并添加了三本书，最后通过标题查询了一本书的信息。

代码如下：

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

class Library:
    def __init__(self, books=None):
        if books is None:
            books = []
        self.books = books

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

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

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

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

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

    def checkout_book(self, book):
        if book.available:
            book.available = False
            return True
        else:
            return False

    def return_book(self, book):
        book.available = True

if __name__ == '__main__':
    library = Library()
    book1 = Book('The Great Gatsby', 'F. Scott Fitzgerald', '978-0143129453')
    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)
    print(library.search_book_by_title('1984'))
