基于控制台的购书系统生成代码

好的，那我可以为您提供一些基本的代码框架，供您参考使用。

首先，我们需要定义一些需要用到的数据结构和变量，例如书目列表、购物车、书目信息等等。代码如下：

# 书目列表
book_list = [
    {"id": 1, "title": "Python编程从入门到实践", "author": "Eric Matthes", "price": 69.9},
    {"id": 2, "title": "流畅的Python", "author": "Luciano Ramalho", "price": 89.0},
    {"id": 3, "title": "Python网络编程攻略", "author": "胡松涛", "price": 68.0},
    {"id": 4, "title": "算法图解", "author": "Aditya Bhargava", "price": 59.0},
    {"id": 5, "title": "深入浅出MySQL", "author": "姜承尧", "price": 69.0}
]

# 购物车
cart = []

# 用户输入的指令
command = ""

# 书目编号
book_id = 0

# 购物车中书目的总价
total_price = 0.0

接下来，我们可以定义一些函数来实现购物系统的各个功能，例如浏览书目、搜索书目、添加购物车、查看购物车、删除书目、结算购物车等等。代码如下：

# 浏览书目
def show_books():
    print("书目列表:")
    for book in book_list:
        print(f"{book['id']}: {book['title']} - {book['author']} - 价格: {book['price']}元")

# 搜索书目
def search_books(keyword):
    for book in book_list:
        if keyword in book['title'] or keyword in book['author']:
            print(f"{book['id']}: {book['title']} - {book['author']} - 价格: {book['price']}元")

# 添加购物车
def add_to_cart(book_id):
    for book in book_list:
        if book['id'] == book_id:
            cart.append(book)
            print(f"{book['title']}已添加到购物车")

# 查看购物车
def show_cart():
    global total_price
    total_price = 0.0
    print("购物车:")
    for book in cart:
        total_price += book['price']
        print(f"{book['id']}: {book['title']} - {book['author']} - 价格: {book['price']}元")
    print(f"总价: {total_price}元")

# 删除书目
def delete_from_cart(book_id):
    for book in cart:
        if book['id'] == book_id:
            cart.remove(book)
            print(f"{book['title']}已从购物车中删除")

# 结算购物车
def checkout():
    global total_price
    if not cart:
        print("购物车为空")
    else:
        print("结算成功")
        print(f"总价: {total_price}元")
        cart.clear()
        total_price = 0.0

最后，我们可以通过一个循环来不断读取用户的输入指令，并根据指令调用相应的函数来实现购物系统的整个流程。代码如下：

while True:
    print("请输入指令:")
    command = input()
    if command == "show":
        show_books()
    elif command.startswith("search "):
        keyword = command.split(" ")[1]
        search_books(keyword)
    elif command.startswith("add "):
        book_id = int(command.split(" ")[1])
        add_to_cart(book_id)
    elif command == "cart":
        show_cart()
    elif command.startswith("delete "):
        book_id = int(command.split(" ")[1])
        delete_from_cart(book_id)
    elif command == "checkout":
        checkout()
        break

以上就是一个简单的基于控制台的购物系统的代码框架，您可以根据自己的需求进行修改和完善。
