Eduard van Valkenburg a2856d3b92 Python: restructure: Python samples into progressive 01-05 layout (#3862)
* restructure: Python samples into progressive 01-05 layout

- 01-get-started/: 6 numbered steps (hello agent → hosting)
- 02-agents/: all agent concept samples (tools, middleware, providers, etc.)
- 03-workflows/: ALL existing workflow samples preserved as-is
- 04-hosting/: azure-functions, durabletask, a2a
- 05-end-to-end/: demos, evaluation, hosted agents
- Old files moved to _to_delete/ for review
- Added AGENTS.md with structure documentation
- autogen-migration/ and semantic-kernel-migration/ preserved at root

* fix: switch to AzureOpenAI Foundry, fix CI failures

- Switch all 01-get-started samples to AzureOpenAIResponsesClient with
  Azure AI Foundry project endpoint (AZURE_AI_PROJECT_ENDPOINT +
  AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME + AzureCliCredential)
- Add _to_delete/ and 05-end-to-end/ to pyrightconfig.samples.json excludes
- Fix test paths in packages/ that referenced old getting_started/ dirs:
  durabletask conftest + streaming test, azurefunctions conftest,
  devui conftest + capture_messages + openai_sdk_integration
- Fix workflow_as_agent_human_in_the_loop.py import (sibling import)
- Update hosting READMEs and tool comment paths
- Replace root README.md with new structure overview
- Update AGENTS.md to document Azure OpenAI Foundry as default provider

* cleanup: remove _to_delete folder, copy resource files to active dirs

All files in _to_delete/ were either:
- Exact duplicates of files in the new structure (240 files)
- Same file with only comment path updates (100 files)
- One import-fix diff (workflow_as_agent_human_in_the_loop.py)
- One superseded minimal_sample.py

Resource files (sample.pdf, countries.json, employees.pdf, weather.json)
copied to 02-agents/sample_assets/ and 02-agents/resources/ since active
samples reference them.

* fix: address PR review comments, centralize resources, remove root duplicates

- Fix type annotation in 04_memory.py (string union -> proper types)
- Fix old sample paths in observability files
- Fix grammar/spelling in observability samples
- Move sample_assets/ and resources/ to shared/ folder
- Remove 8 duplicate observability files from 02-agents root
- Update resource path references in multimodal_input and provider samples

* fix: update broken links from old getting_started paths to new structure

- Update relative paths in READMEs: getting_started/ → 01-get-started/,
  02-agents/, 03-workflows/, 04-hosting/, 05-end-to-end/
- Fix absolute GitHub URLs in package READMEs
- Fix broken link in ollama package README

* fix: convert absolute GitHub URLs to relative paths for link checker

Absolute URLs to python/samples/ on main branch 404 until PR merges.
Converted to relative paths that linkspector can verify locally.

* fix: update link for handoff sample moved to orchestrations/

* fix: update chatkit-integration README path from demos/ to 05-end-to-end/

* fix: update broken links in orchestrations README to match flat directory structure

azure_responses_client.py Direct usage of Azure Responses Client for structured response generation with Azure OpenAI models.
chat_response_cancellation.py Demonstrates how to cancel chat responses during streaming, showing proper cancellation handling and cleanup.
azure_ai_chat_client.py Direct usage of Azure AI Chat Client for chat interactions with Azure AI models.
openai_assistants_client.py Direct usage of OpenAI Assistants Client for basic chat interactions with OpenAI assistants.
openai_chat_client.py Direct usage of OpenAI Chat Client for chat interactions with OpenAI models.
openai_responses_client.py Direct usage of OpenAI Responses Client for structured response generation with OpenAI models.
custom_chat_client.py Demonstrates how to create custom chat clients by extending the BaseChatClient class. Shows a EchoingChatClient implementation and how to integrate it with Agent using the as_agent() method.

Environment Variables

Depending on which client you're using, set the appropriate environment variables:

For Azure clients:

  • AZURE_OPENAI_ENDPOINT: Your Azure OpenAI endpoint
  • AZURE_OPENAI_CHAT_DEPLOYMENT_NAME: The name of your Azure OpenAI chat deployment
  • AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME: The name of your Azure OpenAI responses deployment

For Azure AI client:

  • AZURE_AI_PROJECT_ENDPOINT: Your Azure AI project endpoint
  • AZURE_AI_MODEL_DEPLOYMENT_NAME: The name of your model deployment

For OpenAI clients:

  • OPENAI_API_KEY: Your OpenAI API key
  • OPENAI_CHAT_MODEL_ID: The OpenAI model to use for chat clients (e.g., gpt-4o, gpt-4o-mini, gpt-3.5-turbo)
  • OPENAI_RESPONSES_MODEL_ID: The OpenAI model to use for responses clients (e.g., gpt-4o, gpt-4o-mini, gpt-3.5-turbo)

For Ollama client:

  • OLLAMA_HOST: Your Ollama server URL (defaults to http://localhost:11434 if not set)
  • OLLAMA_MODEL_ID: The Ollama model to use for chat (e.g., llama3.2, llama2, codellama)

Note

: For Ollama, ensure you have Ollama installed and running locally with at least one model downloaded. Visit https://ollama.com/ for installation instructions.
