Python SDK Installation


The Python SDK is installed automatically when you install Hyperledger Sawtooth by following the instructions in Installing and Running Sawtooth. This tutorial explains how import the SDK into your Python environment.


The Sawtooth Python SDK requires Python version 3.5 or higher.


If you install Sawtooth as described in Installing and Running Sawtooth, using the method described in Using Sawtooth on Ubuntu 16.04, then Python is installed for you automatically if it is not already installed.

Importing the SDK

As part of the installation process, the Python SDK is installed and made available through the standard Python import system. From the Python REPL, for example, you could import the SDK and then view the SDK’s docstring:

>>> import sawtooth_sdk
>>> help(sawtooth_sdk)
