基于python的图书管理系统源代码

以下是一个简单的基于 Python 的图书管理系统的源代码。注意，这只是一个示例，实际使用时需要根据需求进行修改和完善。

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)

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

    def search_book(self, title):
        for book in self.books:
            if book.title == title:
                return book
        return None

    def display_books(self):
        for book in self.books:
            print(f"{book.title} by {book.author} (ISBN: {book.isbn})")

library = Library()

while True:
    print("1. Add book")
    print("2. Remove book")
    print("3. Search book")
    print("4. Display all books")
    print("5. Exit")

    choice = input("Enter your choice (1-5): ")
    print()

    if choice == "1":
        title = input("Enter book title: ")
        author = input("Enter book author: ")
        isbn = input("Enter book ISBN: ")
        book = Book(title, author, isbn)
        library.add_book(book)
        print("Book added successfully.")
    elif choice == "2":
        title = input("Enter book title: ")
        book = library.search_book(title)
        if book:
            library.remove_book(book)
            print("Book removed successfully.")
        else:
            print("Book not found.")
    elif choice == "3":
        title = input("Enter book title: ")
        book = library.search_book(title)
        if book:
            print(f"{book.title} by {book.author} (ISBN: {book.isbn})")
        else:
            print("Book not found.")
    elif choice == "4":
        library.display_books()
    elif choice == "5":
        print("Goodbye!")
        break
    else:
        print("Invalid choice. Please try again.")
    print()

上面的代码定义了两个类：`Book` 和 `Library`。`Book` 类表示一本书，包含标题、作者和 ISBN 号等信息。`Library` 类表示一个图书馆，包含一个书籍列表，以及添加、删除、搜索和显示书籍等方法。在主循环中，用户可以选择进行这些操作。
