How can I just use python code to specify the target host instead of the host file？ Do I have to create a new inventory and override the load method?

        self.nr = InitNornir(
            runner={
                "plugin": "serial"        
            },
            inventory={
                "plugin": "SimpleInventory",
                "options": {
                    "host_file": hosts_file_path,
                }    
            },
            logging={"enabled": False},

            dry_run=False
        )

If I understood you right, you can use DictInventory plugin from nornir-salt package https://nornir-salt.readthedocs.io/en/latest/Inventory%20Plugins.html#dictinventory-plugin
