Python Runtime

The Python runtime enables you to execute user-defined Python handlers. It registers a Function kind python and supports three actions: job, serve, and build.

  • job: Execute a Python handler as a one-off job
  • serve: Deploy a Python handler as a long-lived service
  • build: Create a Docker image with all required dependencies for efficient execution

Prerequisites

Supported Python versions:

  • Python ≥ 3.9, < 3.13

Required packages:

  • digitalhub-runtime-python

Install from PyPI:

pip install digitalhub-runtime-python

Usage overview

To execute a Python handler on the platform:

  1. Implement the handler as described in handler definition.
  2. Create a Function resource that references your handler and declares inputs/outputs.
  3. Call function.run() to execute the handler.

See how to for detailed instructions on which actions you can execute and how to configure your Python functions. See Examples for code samples.
