Sending emails is a common requirement in integration scenarios — whether for client reminders, automatic reports, or transaction confirmations. Static messages quickly become hard to maintain and personalize. This is where the templated_email module comes in, combining InterSystems IRIS Interoperability with the power of Jinja2 templates.

Why Jinja2 for Emails

Jinja2 is a popular templating engine from the Python ecosystem that enables fully dynamic content generation. It supports:

• Variables — inject dynamic data from integration messages or external sources
• Conditions (if/else) — change the

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 string.
• __repr__(self):

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.

Exiting the Shell:

>>> quit()

This will exit the Python shell

Modules what a topic! We don't have this notion in ObjectScript, but it's a fundamental concept in Python. Let's discover it together.

What is a Module?

I see modules as an intermediate layer between classes and packages. Let see it by example.

A bad example :

# MyClass.py
class MyClass:
    def my_method(self):
        print("Hello from MyClass!")

When you try to use this class in another script, you would do:

# class_usage.py
from MyClass import MyClass # weird, right?

my_instance = MyClass()
my_instance.my_method()

Why this is a bad example?

First because file names should be in snake_case accor

This will be a short article about PEP 8, the Python style guide.

What is PEP 8?

In a nutshell, PEP 8 provides guidelines and best practices on how to write Python code.

• variable names should be in snake_case
• class names should be in CamelCase
• function names should be in snake_case
• constants should be in UPPER_CASE
• indentation should be 4 spaces (no tabs)
• private variables/functions should start with an underscore (_)
  • because in Python private variables and fonctions doesn't exist, it's just a convention
• your script should not run when imported
  • remember that when you import a script, the

🛠️ Managing InterSystems InterSystems API Manager (IAM = Kong Gateway) configurations in CI/CD

🔍 Context: InterSystems IAM configurations 

As part of integrating InterSystems IRIS into a secure and controlled environment, InterSystems IAM relies on Kong Gateway to manage exposed APIs.
Kong acts as a modern API Gateway, capable of handling authentication, security, traffic management, plugins, and more.

However, maintaining consistent Kong configurations (routes, services, plugins, etc.) across different environments (development, testing, production) is a major challenge. This is where tools like

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:

⏯  Agentic AI in Action: Building a Decision-Making Loop with LLMs

For my intern project, I am building a Flask REST API backend. My goal is to host it on InterSystems IRIS using the WSGI interface. This is a relatively new approach and is currently only being used in a handful of projects such as AskMe. To help others get started, I decided to write this article to simplify the process.

Creating a Basic Flask App

First, let’s create a minimal Flask application. Here is the code:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

@app.route('/test')deftest():return"Test"if __name__ == "__main__":

Hello,

I'm trying to connect a Python backend application to an InterSystems IRIS Community Edition instance running in a Docker container on an AWS EC2 instance. I'm facing persistent connection issues and an SSL Error despite the Superserver apparently having SSL disabled. I'm hoping for some insight into what might be causing this contradictory behavior.

My Setup:

• InterSystems IRIS: Community Edition (Docker image intersystems/iris-community:2025.1)
• Deployment: AWS EC2 (Ubuntu) instance.
• Port Mapping: Host port 9091 mapped to container port 1972 (Superserver). Host port 9092 mapped to

I am writing this post primarily to gather an informal consensus on how developers are using Python in conjunction with IRIS, so please respond to the poll at the end of this article! In the body of the article, I'll give some background on each choice provided, as well as the advantages for each, but feel free to skim over it and just respond to the poll.

As most of you are probably aware, Python is currently the most popular programming language among developers around the world - and for good reason.

If you're migrating from Oracle to InterSystems IRIS—like many of my customers—you may run into Oracle-specific SQL patterns that need translation.

Take this example:

SELECT (TO_DATE('2023-05-12','YYYY-MM-DD') - LEVEL + 1) AS gap_date
FROM dual
CONNECT BY LEVEL <= (TO_DATE('2023-05-12','YYYY-MM-DD') - TO_DATE('2023-05-02','YYYY-MM-DD') + 1);

In Oracle:

• LEVEL is a pseudo-column used in hierarchical queries (CONNECT BY). It starts at 1 and increments by 1.
• CONNECT BY LEVEL <= (...) determines how many rows to generate.
• The difference between the two dates plus one gives 11, so the query

Hello Community

I have previously experimented with embedded Python in IRIS; however, I have not yet had the opportunity to implement IRIS using native Python. In this article, I aim to outline the steps I took to begin learning and implementing IRIS within the Python source. I would also like thank to @Guillaume Rongier and @Luis Angel Pérez Ramos for their help in resolving the issues I encountered during my recent PIP installation of IRIS in Python, which ultimately enabled it to function properly.

Why I've decided to write this

In my last article I've talked about returning values with Python. But returning them is simple, what can make it harder is what I'm going to talk about today: where the value is treated.
 

Python object in IRIS

Following the example of the last aricle, we have the method:

Class python.returnTest [ Abstract ]
{

ClassMethod returnSomething(pValue... As%String) As%Integer [ Language = python ]
{
	return pValue
}

}

Then, we'll have as a return a Python object, that IRIS interprets as  the class %SYS.Python. So if I call the method with two values, like this:

For a long time I have wanted to learn the Django framework, but another more pressing project has always taken priority.Like many developers, I use python when it comes to machine learning, but when I first learned web programming PHP was still enjoying primacy, and so when it was time for me to pick up a new complicated framework for creating web applications to publish my machine learning work, I still turned to PHP.

You know that feeling when you get your blood test results and it all looks like Greek? That's the problem FHIRInsight is here to solve. It started with the idea that medical data shouldn't be scary or confusing – it should be something we can all use. Blood tests are incredibly common for checking our health, but let's be honest, understanding them is tough for most folks, and sometimes even for medical staff who don't specialize in lab work. FHIRInsight wants to make that whole process easier and the information more actionable.

I'm trying to deploy a python/flask application to an Iris4Health container (2025.1) but running into some issues with packages and where they should be installed. 

First one if the flask packages themselves. I tried to installed the flask packages into the python external language server virtual environment, but even doing this when configuring the WSGI application in the web application section, it would complain about not having a WSGI framework. Once I created a custom container and added the flask package at the OS level, I was able to configure the web application without it complaining.
