Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace
%%iris magic for IPython, can run ObjectScript command in Notebooks
It can be run in any Notebook and does not require any special setup on IRIS or the Notebook.
I have table
CREATE TABLE nodes (
name VARCHAR(50) NOT NULL,
parent VARCHAR(50),
PRIMARY KEY (name),
FOREIGN KEY(parent) REFERENCES nodes (name) ON UPDATE cascade
);
I put some data
INSERT INTO nodes (name, parent) VALUES ('n1', NULL);
INSERT INTO nodes (name, parent) VALUES ('n11', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n12', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n13', 'n1');
Let's delete all
DELETE FROM nodes;Nope, no way.
SQL Error [124] [S1000]: [SQLCODE: <-124>:<FOREIGN KEY constraint failed referential check upon DELETE of row in referenced table>] [Location: <ServerLoop>] [%msg: <At least 1 Row exists in table 'SQLUser.nodes' which references key 'NODESPKey2' - Foreign Key Constraint 'NODESFKey3', Field(s) 'parent' failed on referential action of NO ACTION>]
In this GitHub we gather information from a csv, use a DataTransformation to make it into a FHIR object and then, save that information to a FHIR server all that using only Python.
The objective is to show how easy it is to manipulate data into the output we want, here a FHIR Bundle, in the IRIS full Python framework.
I have created a package to export a Global into JSON object file and to re-create it by reloading from this file
embeddedPython refers to the new available technologies. It should be understood as a learning exercise of
how to handle the language interfaces. Only Global nodes containing data are presented in the generated JSON file.
Differently from the previous example, this one is using embedded Python only, no ObjectScript. Therefore PURE
InterSystems Native SDK for Python is a lightweight interface to InterSystems IRIS APIs that were once available only through ObjectScript.
I'm especially interested in the ability to call ObjectScript methods, class methods, to be precise. It works, and it works great, but by default, calls only support scalar arguments: strings, booleans, integers, and floats.
But if you want to:
You'll need to write some glue code or take this project (installs with pip install edpy). edpy package gives you one simple signature:
call(iris, class_name, method_name, args)
which allows you to call any ObjectScript method and get results back.
Frontend development can be a daunting, even nightmarish, task for backend-focused developers. Early in my career, the lines between frontend and backend were blurred, and everyone was expected to handle both. CSS, in particular, was a constant struggle; it felt like an impossible mission.
Although I enjoy frontend work, CSS remains a complex challenge for me, especially since I learned it through trial and error. The meme of Peter Griffin struggling to open blinds perfectly captures my experience of learning CSS.
But today, everything changes.
Hello I am in My 2nd year of Engineering, and want to learn Python Programing Language, Please suggest to me the best books and best online resources that will help me to learn the python language.
Using embedded Python while building your InterSystems-based solution can add very powerful and deep capabilities to your toolbox.
I'd like to share one sample use-case I encountered - enabling a CDC (Change Data Capture) for a mongoDB Collection - capturing those changes, digesting them through an Interoperability flow, and eventually updating an EMR via a REST API.

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 @LuisAngel.PérezRamos 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.
Let's begin to write IRIS in python.
The Web Server Gateway Interface (WSGI) is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python programming language. WSGI is a Python standard described in detail in PEP 3333.
🤔 Ok, great definition and what the point with iris ?
IRIS 2024.2+ has a new feature that allows you to run WSGI applications directly on IRIS. This feature is a great way to integrate IRIS with other Python frameworks and libraries.
Voting time!
Let's cast your votes for the best applications in the InterSystems Python Contest:
How to vote? Details below.
InterSystems has been at the forefront of database technology since its inception, pioneering innovations that consistently outperform competitors like Oracle, IBM, and Microsoft. By focusing on an efficient kernel design and embracing a no-compromise approach to data performance, InterSystems has carved out a niche in mission-critical applications, ensuring reliability, speed, and scalability.
It would be convenient to be able to fetch the whole query result in one operation instead of looping through every row. A fetch_all() method or something similar would provide this functionality I guess. Is there a reason why this is not implemented?
Hey Developers,
It's time to announce the winners of the InterSystems Python contest! Are you ready?
A storm of applause goes to these developers and their applications:
Found a strange documentation block about Python bindings in Chapter 3.6 of the Caché manipulation functions with time and date. It looks like this text accidentally copied one to one of the Perl binging documentation. It's funny that the packages of functions called PTIME_STRUCTPtr, PDATE_STRUCTPtr and PTIMESTAMP_STRUCTPtr is suspicious for Python :)
On the other hand, nothing is said about the functions parse_time, parse_date, parse_timestamp, which are present in /dev/python/intersys/pythonbind.py ahhh!
Has anyone encountered this problem?
For the upcoming Python contest, I would like to make a small demo, on how to create a simple REST application using Python, which will use IRIS as a database. Using this tools
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.
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.
Hi Community,
This post is a introduction of my open exchange iris-climate-change application.
iris-climate-change web application Imports The Food and Agriculture Organization (FAO) Climate Change dataset by using LOAD DATA (SQL) functionality and analyze and visualize data with the help of Python Flask Web Framework, Pandas Python data analysis Library, Plotly Open Source Graphing Library for Python and Plotly JavaScript Open Source Graphing Library.

/iris - Returns a JSON object with the top 10 classes present in the IRISAPP namespace./interop - A ping endpoint to test the interoperability framework of IRIS.Hello everyone, this is with great pleasure that I announce the V2 of my application 'Contest-FHIR'.
In this new version, I used new tools and techniques I discovered at the EUROPEAN HEALTHCARE HACKATHON in which I was invited by InterSystems as a guest and as a mentor to display the multiple projects I did in my intership back in April 2022.
Today I present to you the V2 of my application, it can now transform CSV to FHIR to SQL to JUPYTER notebook.
This is for me a really huge step in InterSystems technologies and I think this tool will be used for many other purpuse and cases.
This is my introduction to a series of posts explaining how to create an end-to-end Machine Learning system.
Our IRIS Development Community has several posts without tags or wrong tagged. As the posts keep growing the organization of each tag and the experience of any community member browsing the subjects tends to decrease.
We can think some usual solutions for this scenario, like:
Hi, I am trying to use embedded python in a cache class, but I can only get it to work in the source code namespace.
We map our client namespaces to our source code namespaces using Default Database for Routines under System > Configuration > Namespaces > Edit Namespace in the management portal.
In the source code namespace:
SOURCENEW>w ##class(EF.helloWorld).helloWorldPython()
Hello World!
SOURCENEW>ZN "EVEXAMPLE"
In the client namespace:
EVEXAMPLE>w ##class(EF.helloWorld).helloWorldPython()
W ##CLASS(EF.helloWorld).
The first full release of our iKnow open-source NLP library is now available on GitHub and PyPI!
The iKnow engine has been available as an InterSystems embedded technology for almost 10 years and the core engine was published to open source earlier this year. Now, in the slipstream of Virtual Summit 2020, we're glad to announce the availability of v1.0, which adds all-Python access to the core engine, documentation and samples on the language model contents and a Jupyter demo notebook to get you started.
Not so long ago, I came across the idea of using Python Class Definition Syntax to create IRIS classes on the InterSystems Ideas Portal. It caught my attention since integrating as many syntaxes as possible gives visibility to InterSystems’s products for programmers with experience in many languages.
The author of that idea pointed out the possibility of creating classes using Python’s syntax, in addition to the currently available ones on IRIS. This concept inspired me to write this article, exploring the possibilities of accessing the full InterSystems power employing only Python.
Cross-Skilling from IRIS objectScript to Python it becomes clear there are some fascinating differences in syntax.
One of these areas was how Python returns Tuples from a method with automatic unpacking.
Effectively this presents as a method that returns multiple values. What an awesome invention :)
out1, out2 = some_function(in1, in2)
ObjectScript has an alternative approach with ByRef and Output parameters.
Do ##class(some_class).SomeMethod(.inAndOut1, in2, .out2)
Where:
The leading dot (".") in front of the variable name passes ByRef and for Output.

In 2017, Forbes published an article talking about API Economy (see: https://www.forbes.com/sites/louiscolumbus/2017/01/29/2017-is-quickly-becoming-the-year-of-the-api-economy/). This article was the trigger to popularize the use of API and API Management by large companies. The article published a maturity model. My understanding is that Intersystems IRIS allows you to reach the top of the pyramid with your current technologies. See the figure above.
For this it is important to combine % CSP.
