• Dapr Python SDK PyPI
• Dapr Python SDK Documentation

Prerequisites:

• Python 3.8+ (Download)
• Dapr Python Client/Server SDK

Installation

Install the Dapr Python SDK via pip:

# Install Dapr client SDK
pip3 install dapr

# Install Dapr gRPC AppCallback service extension
pip3 install dapr-ext-grpc
