物流快递系统 python

物流快递系统的开发需要考虑多个方面，包括订单管理、运输计划、配送路线规划、仓库管理、货物跟踪等等。下面是一个简单的物流快递系统的Python实现的示例代码，供参考：

import datetime

class Order:
    def __init__(self, order_id, sender_name, sender_address, receiver_name, receiver_address, weight):
        self.order_id = order_id
        self.sender_name = sender_name
        self.sender_address = sender_address
        self.receiver_name = receiver_name
        self.receiver_address = receiver_address
        self.weight = weight
        self.status = "Created"
        self.create_time = datetime.datetime.now()

class ShipmentPlan:
    def __init__(self, plan_id, start_time, end_time):
        self.plan_id = plan_id
        self.start_time = start_time
        self.end_time = end_time
        self.orders = []

class DeliveryRoute:
    def __init__(self, route_id, start_location, end_location):
        self.route_id = route_id
        self.start_location = start_location
        self.end_location = end_location
        self.shipment_plans = []

class Warehouse:
    def __init__(self, warehouse_id, location):
        self.warehouse_id = warehouse_id
        self.location = location
        self.orders = []
        self.shipment_plans = []

class LogisticsSystem:
    def __init__(self):
        self.orders = []
        self.shipment_plans = []
        self.delivery_routes = []
        self.warehouses = []

    def create_order(self, sender_name, sender_address, receiver_name, receiver_address, weight):
        order_id = len(self.orders) + 1
        order = Order(order_id, sender_name, sender_address, receiver_name, receiver_address, weight)
        self.orders.append(order)
        return order

    def create_shipment_plan(self, start_time, end_time):
        plan_id = len(self.shipment_plans) + 1
        shipment_plan = ShipmentPlan(plan_id, start_time, end_time)
        self.shipment_plans.append(shipment_plan)
        return shipment_plan

    def create_delivery_route(self, start_location, end_location):
        route_id = len(self.delivery_routes) + 1
        delivery_route = DeliveryRoute(route_id, start_location, end_location)
        self.delivery_routes.append(delivery_route)
        return delivery_route

    def create_warehouse(self, location):
        warehouse_id = len(self.warehouses) + 1
        warehouse = Warehouse(warehouse_id, location)
        self.warehouses.append(warehouse)
        return warehouse

    def add_order_to_warehouse(self, order, warehouse):
        warehouse.orders.append(order)

    def add_shipment_plan_to_warehouse(self, shipment_plan, warehouse):
        warehouse.shipment_plans.append(shipment_plan)

    def add_order_to_shipment_plan(self, order, shipment_plan):
        shipment_plan.orders.append(order)

    def add_shipment_plan_to_delivery_route(self, shipment_plan, delivery_route):
        delivery_route.shipment_plans.append(shipment_plan)

    def get_orders_by_status(self, status):
        return [order for order in self.orders if order.status == status]

    def update_order_status(self, order, status):
        order.status = status

这是一个简单的物流快递系统的Python实现，其中包含了订单管理、运输计划、配送路线规划、仓库管理等基本功能。如果需要更加完整的物流系统，还需要考虑更多的因素，例如货物跟踪、费用计算等等。
