用python写简单的图书管理系统

好的，我可以为您提供一个简单的 Python 图书管理系统的示例代码。您可以根据自己的需求进行修改。

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)
        print("Book added successfully.")

    def remove_book(self, book):
        if book in self.books:
            self.books.remove(book)
            print("Book removed successfully.")
        else:
            print("Book not found in library.")

    def display_books(self):
        for book in self.books:
            print("Title:", book.title)
            print("Author:", book.author)
            print("ISBN:", book.isbn)

if __name__ == "__main__":
    lib = Library()
    while True:
        print("1. Add Book")
        print("2. Remove Book")
        print("3. Display Books")
        print("4. Exit")
        choice = input("Enter your choice: ")
        if choice == "1":
            title = input("Enter book title: ")
            author = input("Enter book author: ")
            isbn = input("Enter book ISBN: ")
            book = Book(title, author, isbn)
            lib.add_book(book)
        elif choice == "2":
            title = input("Enter book title to remove: ")
            book = None
            for b in lib.books:
                if b.title == title:
                    book = b
                    break
            if book:
                lib.remove_book(book)
            else:
                print("Book not found in library.")
        elif choice == "3":
            lib.display_books()
        elif choice == "4":
            break
        else:
            print("Invalid choice. Please try again.")

这个图书管理系统具有添加和删除图书的功能，还可以显示当前库中的所有图书。您可以将其下载并运行，以查看其在控制台中的输出。如果您需要更高级的功能，比如存储库中的书籍列表到文件中，以便在下次运行时进行加载，请告诉我。
