Python client library example

Prerequisites

In order to execute script demonstrating execution of python client library you need to have python 2.7 installed. After that please follow next steps:

1. To compile grpc proto files it is needed to have grpc-io installed:

pip2 install grpcio-tools

./prepare.sh

3. Make sure you have running iroha on your machine. You can follow this guide to launch iroha daemon. Please run iroha from iroha/example folder, since python script uses keys from there.
