构建物管理服务如何创建

class Asset:
    def __init__(self, asset_id, name, location, status):
        self.asset_id = asset_id
        self.name = name
        self.location = location
        self.status = status

class AssetManager:
    def __init__(self):
        self.assets = {}

    def add_asset(self, asset):
        self.assets[asset.asset_id] = asset

    def get_asset(self, asset_id):
        return self.assets.get(asset_id)

    def update_asset_status(self, asset_id, new_status):
        if asset_id in self.assets:
            self.assets[asset_id].status = new_status
            return True
        return False

# 示例使用
asset_manager = AssetManager()
new_asset = Asset(asset_id=1, name="Printer", location="Room 101", status="Active")
asset_manager.add_asset(new_asset)

print(asset_manager.get_asset(1).name)  # 输出: Printer
asset_manager.update_asset_status(1, "Maintenance")
print(asset_manager.get_asset(1).status)  # 输出: Maintenance
