做出根据订单日期客户名称客户类型城市价格以及数量的python项目

好的，以下是一个基于Python的超市订单管理系统的示例代码。这个代码可以实现添加、查看、修改、删除订单等基本功能，同时支持根据日期、客户名称、客户类型、城市、价格、数量等条件进行订单筛选和查询：

import csv

class Order:
    def __init__(self, date, customer_name, customer_type, city, price, quantity):
        self.date = date
        self.customer_name = customer_name
        self.customer_type = customer_type
        self.city = city
        self.price = price
        self.quantity = quantity

class OrderManager:
    def __init__(self):
        self.orders = []
        
    def read_from_file(self, file_name):
        with open(file_name, "r") as f:
            reader = csv.reader(f)
            next(reader) # skip header
            for row in reader:
                order = Order(row[0], row[1], row[2], row[3], float(row[4]), int(row[5]))
                self.orders.append(order)
                
    def write_to_file(self, file_name):
        with open(file_name, "w") as f:
            writer = csv.writer(f)
            writer.writerow(["日期", "客户名称", "客户类型", "城市", "价格", "数量"])
            for order in self.orders:
                writer.writerow([order.date, order.customer_name, order.customer_type, order.city, order.price, order.quantity])
                
    def add_order(self, order):
        self.orders.append(order)
        
    def remove_order(self, order):
        self.orders.remove(order)
        
    def get_orders(self, filters={}):
        filtered_orders = self.orders
        for key, value in filters.items():
            filtered_orders = [order for order in filtered_orders if getattr(order, key) == value]
        return filtered_orders

# 测试代码
order_manager = OrderManager()

# 从文件中读取订单数据
order_manager.read_from_file("orders.csv")

# 添加一个新订单
new_order = Order("2021-05-01", "张三", "个人客户", "北京", 10.0, 100)
order_manager.add_order(new_order)

# 根据日期和客户名称查询订单
filters = {"date": "2021-05-01", "customer_name": "张三"}
orders = order_manager.get_orders(filters)
for order in orders:
    print(order.date, order.customer_name, order.customer_type, order.city, order.price, order.quantity)

# 修改一个订单
order_to_modify = orders[0]
order_to_modify.price = 12.0
order_manager.write_to_file("orders.csv")

# 删除一个订单
order_to_remove = orders[0]
order_manager.remove_order(order_to_remove)
order_manager.write_to_file("orders.csv")

在这个示例代码中，我们定义了一个Order类来表示订单，包含了日期、客户名称、客户类型、城市、价格、数量等属性。我们还定义了一个OrderManager类来管理订单，包括读取、写入、添加、修改、删除订单等基本操作。在OrderManager类中，我们使用了一个列表来存储所有订单。我们可以通过调用get_orders方法，并传入一个filters字典来筛选和查询订单。例如，我们可以通过传入{"date": "2021-05-01", "customer_name": "张三"}来查询指定日期和客户名称的订单。我们还可以通过调用add_order、remove_order等方法来添加、删除订单，通过调用write_to_file方法来将订单数据写入文件中。
