**📣 News: Integration between OpenAI Agents SDK and Temporal is now in public preview. [Learn more](temporalio/contrib/openai_agents/README.md).**

[Temporal](https://temporal.io/) is a distributed, scalable, durable, and highly available orchestration engine used to
execute asynchronous, long-running business logic in a scalable and resilient way.

"Temporal Python SDK" is the framework for authoring workflows and activities using the Python programming language.

Also see:
* [Application Development Guide](https://docs.temporal.io/application-development?lang=python) - Once you've tried our
  [Quick Start](#quick-start), check out our guide on how to use Temporal in your Python applications, including
  information around Temporal core concepts.
* [Python Code Samples](https://github.com/temporalio/samples-python)
* [API Documentation](https://python.temporal.io) - Complete Temporal Python SDK Package reference.

In addition to features common across all Temporal SDKs, the Python SDK also has the following interesting features:

**Type Safe**

This library uses the latest typing and MyPy support with generics to ensure all calls can be typed. For example,
starting a workflow with an `int` parameter when it accepts a `str` parameter would cause MyPy to fail.

**Different Activity Types**

The activity worker has been developed to work with `async def`, threaded, and multiprocess activities. Threaded activities are the initial recommendation, and further guidance can be found in [the docs](https://docs.temporal.io/develop/python/python-sdk-sync-vs-async).

**Custom `asyncio` Event Loop**

The workflow implementation basically turns `async def` functions into workflows backed by a distributed, fault-tolerant
event loop. This means task management, sleep, cancellation, etc have all been developed to seamlessly integrate with
`asyncio` concepts.

See the [blog post](https://temporal.io/blog/durable-distributed-asyncio-event-loop) introducing the Python SDK for an
informal introduction to the features and their implementation.
