Python

Dapr offers a variety of subpackages to help with the development of Python applications. Using them you can create Python clients, servers, and virtual actors with Dapr.

Prerequisites

Installation

To get started with the Python SDK, install the main Dapr Python SDK package.


pip install dapr

Note: The development package will contain features and behavior that will be compatible with the pre-release version of the Dapr runtime. Make sure to uninstall any stable versions of the Python SDK before installing the dapr-dev package.

pip install dapr-dev

Available subpackages

SDK imports

Python SDK imports are subpackages included with the main SDK install, but need to be imported when used. The most common imports provided by the Dapr Python SDK are:

Client

Write Python applications to interact with a Dapr sidecar and other Dapr applications, including stateful virtual actors in Python

Actors

Create and interact with Dapr's Actor framework.

Learn more about all of the available Dapr Python SDK imports.

SDK extensions

SDK extensions mainly work as utilities for receiving pub/sub events, programatically creating pub/sub subscriptions, and handling input binding events. While you can acheive all of these tasks without an extension, using a Python SDK extension proves convenient.

gRPC

Create Dapr services with the gRPC server extension.

FastAPI

Integrate with Dapr Python virtual actors and pub/sub using the Dapr FastAPI extension.

Flask

Integrate with Dapr Python virtual actors using the Dapr Flask extension.

Workflow

Author workflows that work with other Dapr APIs in Python.
