Getting started with the Dapr actor Python SDK

How to get up and running with the Dapr Python SDK

The Dapr actor package allows you to interact with Dapr virtual actors from a Python application.


Actor interface

The interface defines the actor contract that is shared between the actor implementation and the clients calling the actor. Because a client may depend on it, it typically makes sense to define it in an assembly that is separate from the actor implementation.

from import ActorInterface, actormethod

class DemoActorInterface(ActorInterface):
    async def get_my_data(self) -> object:

Actor services

An actor service hosts the virtual actor. It is implemented a class that derives from the base type Actor and implements the interfaces defined in the actor interface.

Actors can be created using one of the Dapr actor extensions:

Actor client

An actor client contains the implementation of the actor client which calls the actor methods defined in the actor interface.

import asyncio

from import ActorProxy, ActorId
from demo_actor_interface import DemoActorInterface

async def main():
    # Create proxy client
    proxy = ActorProxy.create('DemoActor', ActorId('1'), DemoActorInterface)

    # Call method on client
    resp = await proxy.GetMyData()
