#Embedded Python

Hi Community,

We're pleased to invite you to the upcoming webinar in Spanish called "Exploring the new Embedded Python feature of InterSystems IRIS"

Date & Time: March 30, 4:00 PM CEST

Speaker: @Eduardo Anglada, Sales Engineer, InterSystems Iberia

It sounds strange though it's embarrassing.

I have a class with ClassMethods written in ISOS and Embedded Python.

The ClassMethods written in ISOS start in the Background as usual. No problems

But my 

ClassMethod setPy() [ Language = python ]
{
import iris, datetime, time
- - -

Just fails the JOB command with (even 15 sec) timeout and $ZC=0
This is not funny
My actual workaround:
I created a ClassMethod in ISOS, that does an elegant JobStart
and this ClassMethod only runs the Embedded Python ClassMethod.

Hello all,

I've seen that to install any python library we just need to call this:

C:\InterSystems\IRIS\bin>irispip install --target C:\InterSystems\IRIS\mgr\python geopy

Is there a way to install the libraries in a different directory and set up the system to load the python from that other directory?

With the latest improvements in support for Python in IRIS, and continued work on Python DB-API support by InterSystems. I've implemented IRIS support to the Django project where is Python DB-API is used to work with some other databases.

Let's try a simple application on Django, which stores its data in IRIS.

We are happy to share interesting information with you, as well as tell you why Python is good, where it is used.

Among the most used libraries are NumPy and Pandas. NumPy (Numerical Python) is used to sort large datasets. It simplifies mathematical operations and their vectorization on arrays. Pandas offers two data structures: Series (a list of elements) and Data Frames (a table with multiple columns). This library converts data into a Data Frame, allowing you to remove and add new columns, as well as perform various operations.

Hey Developers,

We are pleased to invite you all to the next InterSystems online programming contest focused on Python! 

🏆 InterSystems Python Contest 🏆

Duration: February 7 - 27, 2022

In prizes: $10K - more prizes included!

In my article I described the work using iris.gref .
As the official documetation is rather slim on the subject it was necessary to dig into it.
Using the power of Python I was able to detect what I needed but was hidden.
I decided to share this with you. pydoc did the magic. 

Hi contestants!

Here are the results of the bonus collections the applications of the Python Contest accomplished.

Here are the projects that scored it:

Hi!

Trying to create a string with $LB using Embedded Python.

Don't see the way to do it. If Embedded Python supports list builds?

Hi, Community,

This post will demonstrate how to display data on the web by using Embedded Python , Python Flask Web Framework and Jquery datatable

We will display processes from %SYS.ProcessQuery table.

Step 1: Add table to HTML page and write below javascript code to display passed data from app.py :

HTML

  <table id="myTable" class="table table-bordered table-striped">                 
   </table>

Javascript

  <script>
    
$(document).ready(function() {
      // parse the data to local variable passed from app.py file
      let my_data = JSON.parse('{{ my_data | tojson }}');
      let my_cols = JSON.parse('{{ my_cols | tojson }}');

      $('#myTable').DataTable( {
          "data": my_data,
          "columns": my_cols,"} );
     } );

Python is 31 today ; let’s celebrate it 🎂 

And special thanks to Guido van Rossum 

Hi Community,

This post is a introduction of my openexchange iris-python-apps application. Build by using Embedded Python and Python Flask Web Framework. 
Application also demonstrates some of the Python functionalities like Data Science, Data Plotting, Data Visualization and QR Code generation.

 Features

•  Responsive bootstrap IRIS Dashboard

•  View dashboard details along with interoperability events log and messages.

•  Use of Python plotting from IRIS

•  Use of Jupyter Notebook

•  Introduction to Data Science, Data Plotting and Data Visualization.

•  QR Code generator from python.

Hey Developers, 

In this video, you will learn how to use VS Code with Python: 

⏯ Using VS Code with Python

If your embedded python code calls tkinter library (which is used by a lot of graphic producing libraries, including matplotlib), you might get this error:

<THROW> *%Exception.PythonException <CLASS DOES NOT EXIST> 230 ^^0^DO ##CLASS(User.Test).Test() 
<class '_tkinter.TclError'>: Can't find a usable init.tcl in the following directories:

c:/intersystems/irispy/lib/python/lib/tcl8.6

c:/intersystems/lib/tcl8.6
c:/intersystems/irispy/library
c:/intersystems/library
c:/intersystems/tcl8.6.9/library
c:/tcl8.6.9/library

This probably means that Tcl wasn't installed properly.

I will give you some additional information on my first embedded Python package.
it is written as a mix of python and ObjectScript to take the best of both worlds.

Hi Community,

We are pleased to invite all the developers to the upcoming InterSystems Python Contest Kick-off Webinar! The topic of this webinar is dedicated to the Python contest.

In this webinar, we’ll present two templates to start working with Embedded Python :

Hi all - we just released the first episode of Season 2 for our Data Points podcast by Learning Services. This episode features a conversation with @Bob Kuszewski about Embedded Python. If you're a Python developer, or if you're simply interested in the functionality, check it out! For more information, head over to https://datapoints.intersystems.com.

From IRIS 2021.2 is possible write Class Methods using the Python Language. I used this new feature to detect persons and objects into images, using ImageAI (https://github.com/OlafenwaMoses/ImageAI). The ImageAI creator defines it as: "An open-source python library built to empower developers to build applications and systems with self-contained Deep Learning and Computer Vision capabilities using simple and few lines of code." In this article you will learn how to apply AI Computer Vision to detect object and persons inside images.

Hi,

What is the Python syntax I can use from a ClassMethod (developed in an IRIS using embedded Python), in order to invoke another class method,

- in the same class; and

- in another class.

I see 'self' is synonymous to use $this (..) in ObjectScript, but these are ClassMethods I am invoking, and self did not seem to work.

thanks - Steve

I'd like to share an example on how the new Embedded Python feature in IRIS helped me in my daily routines.

While I’m participating in the iris-kaggle-socrata-generator project with Henrique Dias, I got to unzip datasets from Kaggle in order to import them.

Such a task was easily achieved by using the zipfile lib in Python (this code was copied from this stackoverflow):

Method UnZip(pZipFileName As %String, pExtractToDir As %String) As %DynamicArray [ Language = python ]
{
    import zipfile
    import iris
    with zipfile.ZipFile(pZipFileName, 'r') as zip_ref:
        zip_ref.extractall(pExtractToDir)
        fileList = zip_ref.namelist()
    
    dynarray = iris.cls("%DynamicArray")._New()
    for file in fileList:
        dynarray._Push(file)
    return dynarray
}

If you develop in IRIS you are confronted with two major phenomena:

• an incredibly fast and excellent designed data storage engine
• a scripting language to work on this storage engine, actually named ObjectScript
