如何定义一个包含图书信息（书号、书名、价格）的顺序表 python

要定义一个包含图书信息（书号、书名、价格）的顺序表，可以使用Python的列表来实现。每个元素代表一本图书，包含书号、书名和价格三个属性。以下是一个示例代码：

# 定义一个包含图书信息的顺序表
book_list = []

# 添加图书信息
def add_book(book_list, book_no, book_name, price):
    book = [book_no, book_name, price]
    book_list.append(book)

# 创建图书信息表
add_book(book_list, 1, "Book A", 10.99)
add_book(book_list, 2, "Book B", 15.99)
add_book(book_list, 3, "Book C", 12.99)

# 计算所有图书的平均价格
def calculate_average_price(book_list):
    total_price = 0
    for book in book_list:
        total_price += book[2]
    average_price = total_price / len(book_list)
    return average_price

average_price = calculate_average_price(book_list)

# 提高低于平均价格的图书价格20%
def increase_price(book_list, average_price):
    for book in book_list:
        if book[2] < average_price:
            book[2] *= 1.2

increase_price(book_list, average_price)

# 打印图书信息表
for book in book_list:
    print("书号:", book[0], "书名:", book[1], "价格:", book[2])
