python图书管理系统代码

以下是一个简单的Python图书管理系统代码：

books = []

def add_book():
    title = input("Enter book title: ")
    author = input("Enter book author: ")
    year = input("Enter publication year: ")
    book = {"title": title, "author": author, "year": year}
    books.append(book)
    print("Book added successfully.")

def remove_book():
    title = input("Enter book title to remove: ")
    for book in books:
        if book["title"] == title:
            books.remove(book)
            print("Book removed successfully.")
            return
    print("Book not found.")

def view_books():
    for book in books:
        print(f"{book['title']} by {book['author']} ({book['year']})")

while True:
    print("""
    1. Add Book
    2. Remove Book
    3. View Books
    4. Exit
    """)
    choice = input("Enter choice: ")
    if choice == "1":
        add_book()
    elif choice == "2":
        remove_book()
    elif choice == "3":
        view_books()
    elif choice == "4":
        break
    else:
        print("Invalid choice. Please try again.")

这个程序使用一个包含字典的列表来存储书籍信息。用户可以选择添加、删除或查看书籍。程序使用无限循环和条件语句来实现这些功能。
