# Hello Query Device Python* Sample {#openvino_inference_engine_ie_bridges_python_sample_hello_query_device_README}
|
||||
|
||||
This sample demonstrates how to show OpenVINO™ Runtime devices and prints their metrics and default configuration values using [Query Device API feature](../../../docs/OV_Runtime_UG/supported_plugins/config_properties.md).

This sample demonstrates how to show OpenVINO™ Runtime devices and prints their metrics and default configuration values using :doc:`Query Device API feature <openvino_docs_OV_UG_query_api>`.
|

The following Python API is used in the application:

## How It Works
|
||||
How It Works
|
||||
############
|
||||
|
||||
The sample queries all available OpenVINO™ Runtime devices and prints their supported metrics and plugin configuration parameters.
|
||||
|
||||
## Running

#######
|
||||
|
||||
The sample has no command-line parameters. To see the report, run the following command:
|
||||
|
||||
```
|
||||
python hello_query_device.py
|
||||
```
|
||||
.. code-block:: console
|
||||
|
||||
python hello_query_device.py
|
