Python Samples

File Structure

Every sample file follows this order:

1. PEP 723 inline script metadata (if external dependencies needed)
2. Copyright header: # Copyright (c) Microsoft. All rights reserved.
3. Required imports
4. Module docstring: """This sample demonstrates..."""
5. Helper functions
6. Main function(s) demonstrating functionality
7. Entry point: if __name__ == "__main__": asyncio.run(main())

External Dependencies

Use PEP 723 inline script metadata for external packages not in the dev environment:

# /// script
# requires-python = ">=3.10"
# dependencies = [
#     "some-external-package",
# ]
# ///
# Run with: uv run samples/path/to/script.py
 
# Copyright (c) Microsoft. All rights reserved.

Do not add sample-only dependencies to the root pyproject.toml dev group.

Syntax Checking

# Format + lint samples
uv run poe syntax -S
 
# Check samples for syntax errors and missing imports
uv

Documentation

Samples should be over-documented:

1. Include a README.md in each set of samples
2. Add a summary docstring under imports explaining the purpose and key components
3. Mark code sections with numbered comments:

   # 1. Create the client instance.
   ...
   # 2. Create the agent with the client.
   ...
4. Include expected output at the end of the file:

   """
   Sample output:
   User:> Why is the sky blue?
   Assistant:> The sky is blue due to Rayleigh scattering...
   """

Guidelines

• Incremental complexity — start simple, build up (step1, step2, ...)
• Getting started naming: step<number>_<name>.py
• When modifying samples, update associated README files
