Let's say you have Python including variable-length arguments methods. How can you call it from ObjectScript? 

def test1(*args):
  return sum(args)
  
def test2(**kwargs):
  a1 = kwargs.get("a1",None)
  a2 = kwargs.get("a2",None)
  return a1+a2

You can call this "a.py" from ObjectScript as below.  For **kwargs argument, create Dynamic Object in ObjectScript and put it into methods with <variablename>... (3 dots) format. 

    set a=##class(%SYS.Python).Import("a")
    write a.test1(1,2,3)   ;; 6
    set req={}
    set req.a1=10
    set req.a2=20
    write a.

Hi folks!

Just want to introduce you a new util to import CSV into IRIS - csvgenpy!

Install

USER>zpm "install csvgenpy"

Use:

do ##class(shvarov.csvgenpy.csv).Generate("file or url","table","schema")

Example:

USER>do ##class(shvarov.csvgenpy.csv).Generate("https://raw.githubusercontent.com/datasciencedojo/datasets/master/titanic.csv","titanic","data")

This will create table and class data.titanic in IRIS and will load the data.  you can proof it with:

USER>:sql

[SQL]USER>>select * from data.titanic

[SQL]USER>>select * from data.titanic

1. select * from data.

Hello,

I became aware of Python in the early 2000s when I started automating tasks. Some of our processes utilized python scripts. I never figured it out very well, and we decided to do away with Python because nobody on our team was familiar with it.

Along the way, I heard a lot about Python. My interest was renewed when InterSystems offered bonus points for using Python in contests.

The things I like the most about Python so far is how easy it is to find the mean of the ages of all Titanic passengers. For my test-data app I wanted to find the largest value in the ‘Qty’ column in a CSV file.

Introduction

In InterSystems IRIS 2024.3 and subsequent IRIS versions, the AutoML component is now delivered as a separate Python package that is installed after installation. Unfortunately, some recent versions of Python packages that AutoML relies on have introduced incompatibilities, and can cause failures when training models (TRAIN MODEL statement). If you see an error mentioning "TypeError" and the keyword argument "fit_params" or "sklearn_tags", read on for a quick fix.

Root Cause

  • scikit-learn updated to version 1.6.0, deprecating fit_params.

Recently, I come up an idea in my mind that how can I put my playlist on IRIS.🧐

At the same time, I was told to pay for my Spotify subscription💸💸... ooo.. how about to get some data from the Spotify API... so I started to do study about it.

 

Like most of the development, let's start from Documentation of  the API https://developer.spotify.com/documentation/web-api

In order to get the data, i am required to request an access token from for the token endpoint URL.🧐

As a part of the IRIS Python 2024 contest, my colleague Damir and I went with an idea to build a platform called ShelterShare for connecting victims and volunteers for shelter requests . To do so we chose django as a framework and proceeded to build the first version with 3 different docker containers, django, iris and nginx which would then utilize IRIS as a pure Database engine via the beautifly composed django_iris (cudos to Dimitry). As we were progressing fast, we decided to explore the option of running it within the same container as IRIS by utilizing WSGI added in 2024.1.

image Hello to all developers and IRIS users. I am submitting to the competition a project for an alternative IRIS management portal that I have long wanted to create. The project was implemented on the Django framework and the intersystems_irispython-3.2.0-py3-none-any.whl library using native IRIS. The Django project is integrated with the telegram messenger and can be launched from a docker container or directly. To run it, you need to create a .env file in the project root for which you can use the .env_example example.

Hello interface engineers and app developers,     

Did you know that you can use Python in productions or integrations?

The production configuration user interface is low-code, but in many projects, you may reach a point where you need to write some code. As discussed in the Integration Architecture course, business processes are full of places for inserting code, specifically the BPL editor (for BPL business processes) and the DTL editor (for data transformations).

😯 As of InterSystems IRIS 2025.1, both Python and InterSystems ObjectScript are supported in the BPL and DTL editors.

Reviewing my published packages, I identified a nasty bug in IRIS Native API

  • There is a method in  %Net.DB.Iris named function ()
  • It's equivalent to  ObjectScript $$label^routine(param) 
  • It used to work fine 2 years ago, when I published my command-line-extension packages
  • Now it is broken since at least 1 year and throws <PROTECT>
  • I identified it for ObjecScript, Java, Python, Node.js
  • It is reported as WRC# 1002589
  • For all 4 cases, I also verified a workaround
    • Instead of calling an ObjectScript Function you call a Classmethod
    • It's by %Net.DB.Iris ClassMethodValue(.

The diverse crew of the USS Enterprise, each masterminding their unique roles, is a perfect metaphor for understanding AI agents and their power in projects like Facilis.

This is a demo of IRIS Native API for Python, which uses Python to call the Object Script method and flow the message in production. Python obtains the message after flow and the message in global, and uses ZPM Package deployment.

 

Firstly, we need to install the Native API package

 

Enter on the command line

 

pip install intersystems_irispython-3.2.0-py3-none-any.

Are you curious about how to run Python scripts directly in your InterSystems IRIS or Caché terminal? 🤔 Good news it's easy! 😆 IRIS supports Embedded Python, allowing you to use Python interactively within its terminal environment. 

How to access the Python Shell?

To launch the Python shell from the IRIS terminal, simply run the following command:

do ##class(%SYS.Python).Shell()

This opens an interactive Python shell inside the IRIS terminal. From here, you can write and run Python code just as you would in a normal Python environment.

How Python works

Interpreted Language

Python is an interpreted language, which means that the code is executed line by line at runtime even when you import a script.

What does this mean ? Let's take a look at the following code:

Hi Community,

In the first part of this series, we examined the fundamentals of Interoperability on Python (IoP), specifically how it enables us to construct such interoperability elements as business services, processes, and operations using pure Python.

Now, we are ready to take things a step further. Real-world integration scenarios extend beyond simple message handoffs.They involve scheduled polling, custom message structures, decision logic, filtering, and configuration handling.In this article, we will delve into these more advanced IoP capabilities and demonstrate how to create and run a more complex interoperability flow using only Python.

To make it practical, we will build a comprehensive example: The Reddit Post Analyzer Production. The concept is straightforward: continuously retrieving the latest submissions from a chosen subreddit, filtering them based on popularity, adding extra tags to them, and sending them off for storage or further analysis.

The ultimate goal here is a reliable, self-running data ingestion pipeline. All major parts (the Business Service, Business Process, and Business Operation) are implemented in Python, showcasing how to use IoP as a Python-first integration methodology.

This will be a short article about Python dunder methods, also known as magic methods.

What are Dunder Methods?

Dunder methods are special methods in Python that start and end with double underscores (__). They allow you to define the behavior of your objects for built-in operations, such as addition, subtraction, string representation, and more.

Some common dunder methods include:

  • __init__(self, ...): Called when an object is created.
    • Like our %OnNew method in ObjectScript.
  • __str__(self): Called by the str() built-in function and print to represent the object as a

Within IRIS I defined a task to export audit data every day.

I provide some sample files in my GitHub repo.

I wrote ObjectScript code to import all files into otw.audit.consolidator class.

 

I want to use Python SQLAlchemy, pandas and sqlalchemy-iris (created by Dmitry Maslenikov) to copy consolidated audit data from my consolidator class in my IRIS container to my InterSystems Cloud SQL deployment.

 

I updated my Dockerfile to pip3 install sqlalchemy-iris and pandas (dataframes).

 

docker-compose build –no-cache in my personal AWS took 700 seconds.

We have a rule to disable a user account if they have not logged in for a certain number of days. IRIS Audit database logs many events such as login failures for example. It can be configured to log successful logins as well. We have IRIS clusters with many IRIS instances. I like to run queries against audit data from ALL IRIS instances and identify user accounts which have not logged into ANY IRIS instance.
