# Hello Query Device Python Sample

This sample demonstrates how to show OpenVINO™ Runtime devices and prints their metrics and default configuration values using [Query Device API feature](https://docs.openvino.ai/2025/openvino-workflow/running-inference/inference-devices-and-modes/query-device-properties.html).
