# Python Workflows SDK

Workflow entrypoints can be declared using Python. To achieve this, you can export a `WorkflowEntrypoint` that runs on the Cloudflare Workers platform. Refer to [Python Workers](https://developers.cloudflare.com/workers/languages/python) for more information about Python on the Workers runtime.

Python Workflows are in beta, as well as the underlying platform.

Join the #python-workers channel in the [Cloudflare Developers Discord ↗](https://discord.cloudflare.com/) and let us know what you'd like to see next.

## Get Started

The main entrypoint for a Python workflow is the [WorkflowEntrypoint](https://developers.cloudflare.com/workflows/build/workers-api/#workflowentrypoint) class. Your workflow logic should exist inside the [run](https://developers.cloudflare.com/workflows/build/workers-api/#run) handler.

Python

```
from workers import WorkflowEntrypoint
class MyWorkflow(WorkflowEntrypoint):    async def run(self, event, step):        # steps here
```

For example, a Workflow may be defined as:

Python

```
from workers import Response, WorkflowEntrypoint, WorkerEntrypoint
class PythonWorkflowStarter(WorkflowEntrypoint):    async def run(self, event, step):
        @step.do('step1')        async def step_1():            # does stuff            print('executing step1')
        @step.do('step2')        async def step_2():            # does stuff            print('executing step2')
        await step_1()        await step_2()
class Default(WorkerEntrypoint):    async def fetch(self, request):        await self.env.MY_WORKFLOW.create()        return Response("Hello world!")
```

You must add both `python_workflows` and `python_workers` compatibility flags to your Wrangler configuration file.

* [  wrangler.jsonc ](#tab-panel-13405)
* [  wrangler.toml ](#tab-panel-13406)

JSONC

```
{  "$schema": "./node_modules/wrangler/config-schema.json",  "name": "hello-python",  "main": "src/entry.py",  "compatibility_flags": [    "python_workers",    "python_workflows"  ],  // Set this to today's date  "compatibility_date": "2026-06-28",  "workflows": [    {      "name": "workflows-demo",      "binding": "MY_WORKFLOW",      "class_name": "PythonWorkflowStarter"    }  ]}
```

TOML

```
"$schema" = "./node_modules/wrangler/config-schema.json"name = "hello-python"main = "src/entry.py"compatibility_flags = [ "python_workers", "python_workflows" ]# Set this to today's datecompatibility_date = "2026-06-28"
[[workflows]]name = "workflows-demo"binding = "MY_WORKFLOW"class_name = "PythonWorkflowStarter"
```

To run a Python Workflow locally, use [Wrangler](https://developers.cloudflare.com/workers/wrangler/), the CLI for Cloudflare Workers:

Terminal window

```
npx wrangler@latest dev
```

To deploy a Python Workflow to Cloudflare, run [wrangler deploy](https://developers.cloudflare.com/workers/wrangler/commands/general/#deploy):

Terminal window

```
npx wrangler@latest deploy
```
