python体育用品销售管理系统代码

创建一个Python体育用品销售管理系统涉及到多个模块，包括用户管理、商品管理、订单处理和库存跟踪等。以下是一个简化的概念框架，而不是完整的代码：

# 导入必要的库
import os
from datetime import datetime

class User:
    def __init__(self, name, email, password):
        self.name = name
        self.email = email
        self.password = password

class Product:
    def __init__(self, id, name, price, stock):
        self.id = id
        self.name = name
        self.price = price
        self.stock = stock

class InventoryManager:
    def __init__(self):
        self.products = {}  # 商品字典，id为键

    def add_product(self, product):
        self.products[product.id] = product

    def remove_product(self, product_id):
        if product_id in self.products:
            del self.products[product_id]

class ShoppingCart:
    def __init__(self):
        self.items = {}

    def add_item(self, user, product_id, quantity):
        if user not in self.items:
            self.items[user] = {}
        self.items[user][product_id] = quantity

    def remove_item(self, user, product_id):
        if user in self.items and product_id in self.items[user]:
            del self.items[user][product_id]

class SalesOrder:
    def __init__(self, user, items, order_date):
        self.user = user
        self.items = items
        self.order_date = order_date

    def calculate_total(self):
        total = sum(product.price * quantity for product_id, quantity in self.items.items())
        return total

def main():
    # 初始化管理器
    inventory_manager = InventoryManager()

    # 添加产品示例
    product1 = Product(1, "Nike Running Shoes", 99.99, 10)
    inventory_manager.add_product(product1)

    # 用户操作示例
    user = User("John Doe", "john.doe@example.com", "password")
    cart = ShoppingCart()
    cart.add_item(user, product1.id, 2)

    # 创建订单并计算总金额
    order = SalesOrder(user, cart.items, datetime.now())
    total = order.calculate_total()

    print(f"Order for {user.name}: Total = ${total:.2f}")

if __name__ == "__main__":
    main()
