What this trail covers

The Python SDK is now generally available, offering developers a robust way to build durable workflows and activities using Python's asyncio. This post details the core components: workflow definitions, activity implementations, and the worker setup for executing these tasks. It emphasizes best practices like using dataclasses for input and understanding the roles of the client and worker in interacting with the Temporal Server.

All Temporal trails
  1. Temporal Python SDK | Durable Asyncio Event LoopThis post announces the General Availability (GA) release of the Temporal Python SDK. It details how the SDK leverages Python's native asyncio constructs for durable workflows, making it a natural fit for Python developers. The post provides code examples for implementing activities and workflows, demonstrating the use of `asyncio.sleep` for durable timers and the integration with the Temporal client. It also explains how Temporal workflows function as asyncio event loops, ensuring durability and resumability even after process crashes.
  2. Getting Started with Python SDKThis post provides a practical "getting started" guide for the Temporal Python SDK, demonstrating its use through a poker game application. It covers the basic steps of connecting to the Temporal Server, enabling a worker, creating a workflow, and creating an activity. The author emphasizes a hands-on learning approach and highlights the benefits of using an IDE like PyCharm for development. It also points to community resources for troubleshooting and further learning.
  3. Temporal Python SDK: Diving into Workers and WorkflowsThis post provides a practical, step-by-step guide to using the GA Python SDK. It breaks down the structure of a basic Temporal application into `workflow.py` and `worker.py`, demonstrating how to define workflows and activities, configure a client connection, and set up a worker to process tasks. It highlights the use of decorators for registering workflows and activities, the `execute_activity` method with timeouts, and the client's role in starting workflows.
  4. Temporal Python SDK ReleaseThis post announces the general availability of the Temporal Python SDK. It covers installation of the Temporal CLI and the Python package, setup of a local development environment using `temporal server start-dev`, and provides a basic usage example (`hello_activity.py`) demonstrating a simple workflow and activity. It also links to further learning resources and community channels.
