archimedes-python-client 4.20.3

The Python library for Archimedes

archimedes-python-client

archimedes is the python sdk for accessing Optimeering data. This document outlines the setup of environment, authentication and general usage of the python client to fetch RK within day data using python.

Setting up the environment

We will be using venv to manage the virtual environment in this example.

Creating a virtual environment.

python3 -m venv .venv

This will create a directory named .venv where all the dependencies will be installed.

Activating the virtual environment

source ./.venv/bin/activate # linux/macOS
.venv\Scripts\activate.bat # Windows cmd
.\.venv\Scripts\Activate.ps1 # Windows PowerShell

Installingarchimedes-python-client

python3 -m pip install archimedes-python-client

Authentication

For local development:

For local development, the python client can use user authentication. The users are can be authenticated using the archimedes command line tool arcl.

python3 -m pip install arcl

arcl auth login # then, follow the instructions to login with your Microsoft account

Once the user is logged in, the archimedes login information will be stored in your ~/.archimedes directory and all the scripts and applications running as the same user are able to authenticate to the API automatically when using the archimedes-python-client.

For deployed applications:

The python client uses the following fields in environment variable for authentication of the client.

1. AZURE_AD_TENANT_ID Provided by Optimeering AS
2. AZURE_AD_APP_ID Provided by Optimeering AS
3. AZURE_AD_APP_CLIENT_CREDENTIAL Provided by Optimeering AS
4. USE_APP_AUTHENTICATION Set to True

As long as these variables have been set up as environment variables, any python script that invokes methods in archimedes will automatically use the values in the environment variables for authentication.

Example Code

Below is a code sample that invokes an archimedes method.

#import os
import archimedes

# The following environment variables are only needed for deployed applications.
# These would ideally be set in the app runtime environment and not necessarily in 
# python code
# os.environ["AZURE_AD_TENANT_ID"] = "***azure_ad_tenant_id***"
# os.environ["AZURE_AD_APP_ID"] = "***azure_ad_client_id***"
# os.environ["AZURE_AD_APP_CLIENT_CREDENTIAL"] = "***secret***"
# os.environ["USE_APP_AUTHENTICATION"] = "true"

data = archimedes.rk_within_day.directions(
    start="2023-01-01 00:00:00+0000",
    price_area="NO1",
    end="2023-01-01 01:00:00+0000",
    ref_dt="2022-12-31 23:00:00+0000"
)
print(data)

The sample code prints the RK within day directions probability for provided constraints to the console.
