What is Web Scraping:

In simple terms, Web scraping, web harvesting, or web data extraction is an automated process of collecting large data(unstructured) from websites. The user can extract all the data on particular sites or the specific data as per the requirement. The data collected can be stored in a structured format for further analysis.

Steps involved in web scraping:

1. Find the URL of the webpage that you want to scrape
2. Select the particular elements by inspecting
3. Write the code to get the content of the selected elements
4. Store the data in the required format

It’s that simple !

Hi Community, 

Let's meet virtually at our Third Community Roundtable! This will be a 60-min discussion on a given topic: Developing with Python. 

Register through >> this Global Masters challenge << 

UPDATE: the roundtable recording is available here.

TL;DR: This article describes an introductory-level project that exercises some string-manipulation functions in both ObjectScript and Python…with specs from a song.

After you’ve written your first “Hello World!” program, are you ready for a new fun challenge?  An old, very popular (at the time) song may be just what you need.

While I was driving around on vacation in southern Maine, the local “Legends” radio station played the old classic, “The Name Game” by Shirley Ellis (https://www.youtube.com/watch?v=5MJLi5_dyn0).

Hi Community,

In this article I will explain how to display management portal dashboard by using Python Flask web and Boostrap framework with the help of embedded python

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Using Python with InterSystems IRIS @ Global Summit 2022

Hey Developers,

Watch this video to learn how InterSystems IRIS users are deploying Embedded Python to speed their application development:

⏯ Embedded Python Use Cases @ Global Summit 2022

Hi, devs!

In ObjectScript I can refer to a class parameter as:

write ..#ParameterName

How do I do the same in Embedded Python?

Introduction

This article aims to give an introduction to what gRPC is and an example of how to play with the official Hello World using IRIS Embedded Python.

You can find all the code exposed here, in this project repo.

gRPC

The gRPC (gRPC remote procedure call) is an API architectural style based on the RPC protocol. The project was created by Google in 2015 and is licensed under Apache 2.0. Currently, the project is supported by the Cloud Native Computing Foundation (CNCF).

Overview

We started to use Azure Service Bus (ASB) as an enterprise messaging solution 3 years ago. It is being used to publish and consume data between many applications in the organization. Since the data flow is complex, and one application’s data is usually needed in multi applications the “publisher” ---> ”multiple subscribers” model was a great fit. The ASB usage in the organization is dozens of millions of messages per day, while IRIS platform is having around 2-3 million messages/day.

Hi developers!

Those who code IRIS solutions in VSCode using Docker often use the convenient ObjectScript menu, which contains links to Management Portal, Class Reference, Unittest portal, Productions, etc.

While drilling down to a Dev Container to code Embedded Python there is no such option, at least within my settings:

So I don't know how to connect to it. 

Thoughts?

Hi developers!

Let me share with you a minimal embedded python template, that I can recommend as a starting point for any general project with InterSystems IRIS that will use embedded python.

Features:

• Embedded Python ready;
• Examples of 3 ways of Embedded python development;
• VSCode development ready;
• Docker enabled;
• Online demo enabled;
• ZPM First development ready.

Let's discuss the features below!

Hi, devs!

What's the way to call the methods of %SYSTEM class from python?

I tried this way:

print(iris.cls('_SYSTEM.OBJ'

and getting an error:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
RuntimeError: iris.class: error finding class

Here is how it works in ObjectScript:

USER>w

Thoughts?

Hi folks!

I'm playing with Embedded python with IRIS trying to do some 'hello-world' exercises.

I'm running IRIS in container and have the following python code:

# Program to test coding with IRIS'Hello World'# Run IRIS Class Method 

So, when I execute it, I get the following:

$ /usr/irissys/bin/irispython /irisrun/repo/python/app.py
Hello World
Traceback (most recent call last):
  File "/irisrun/repo/python/app.py", line 7, in <module>
    import iris
  File "/usr/irissys/lib/python/iris.py", line 14, in <module>
    from pythonint import *
ImportError: IrisStart failed: IRIS_ACCESSDENIED (-15)

In this GitHub based on this InterSystems community rest api template Guillaume and I have created this example of all the import CRUD operations usable using ONLY Python on IRIS and using Flask.

Using the IRIS ORM or by simply doing SQL requests as both methods are seen in the GitHub.

1. intersystems-iris-docker-rest-template

This is a template of a REST API application built in python in InterSystems IRIS. It also has OPEN API spec, can be developed with Docker and VSCode.

Easy, easy, I'm not promoting a war against the machines in the best sci-fi way to avoid world domination of Ultron or Skynet. Not yet, not yet 🤔

I invite you to challenge the machines through the creation of a very simple game using ObjectScript with embedded Python.

I have to say that I got super excited with the feature of Embedded Python on InterSystems IRIS, it's incredible the bunch of possibilities that opens to create fantastic apps.

Let's build a tic tac toe, the rules are quite simple and I believe that everyone knows how to play.

Folks!

Could you please share any best practices on how to debug Embedded Python code?

Given I have the following class method:

ClassMethod HideShip() As %Status [ Language = python ]
{
    import"BoardStorage"

And when I run it shows the following error:

USER>d ##class(eshvarov.sample.SeaBattle.GamePython).HideShip()

D ##CLASS(eshvarov.sample.SeaBattle.GamePython).HideShip()
^
<THROW> *%Exception.PythonException <THROW> 230 ^^0^D ##CLASS(eshvarov.sample.SeaBattle.GamePython).HideShip() <class 'KeyError'>: Invalid args -

Hi, devs!

Consider you have an arbitrary global with an unknown amount of indexes.

How to print all the values to the terminal with Embedded Python?

Hi folks!

I'm working with a global via Embedded Python as a class method. I init the handler for a global via:

gl=iris.gref("^Global"

What is the way to check the value at index ^Global("x","y")? E.g.:

In ObjectScript I'd do the following:

set^Global

How do I do the same in Embedded Python?

I checked the documentation, but haven't found an answer.

Hi Community, 

Join us for an InterSystems Developer Meetup during TechCrunch Disrupt 2022!

We’ll be meeting on Wednesday, October 19th at Bartlett Hall, located at 242 O’Farrell St. (just a few short blocks from the Moscone Center) starting at 6 pm through 8:30 pm PT, where speakers will discuss how developers can bring the code to the data, not data to the code with Embedded Python and Integrated ML on InterSystems IRIS.

Food and drinks will be served accompanied by discussions. 

Agenda:

grpc-iris-interop

The aim of this proof of concept is to show how the gRPC protocl can be implemented with the IRIS ineroperabilty module.

architecture

On this schema, we can see that the gRPC Service is hosted by IRIS.

This service must invoke the IRIS interoperability module. For that it transforms the protobuf messages to IRIS messages.

The gRPC client is host by a Flask server for demo purpose, the gRPC client can also be invoke by the python script.

definition of each file

users.proto

syntax = "proto3";
package users;

service Users {
  rpc CreateUser (users.CreateUserRequest) returns (users.CreateUserResponse);
  rpc GetUser (users.GetUserRequest) returns (users.GetUserResponse);
}

message User {
  uint32 id = 1;
  string name = 2;
  string dob = 3;
  string company = 4;
  string phone = 5;
  string title = 6;

}

message CreateUserRequest {
  User user = 1;
}

message CreateUserResponse {
  User user = 1;
}

message GetUserRequest {
  uint32 id = 1;
}

message GetUserResponse {
  User user = 1;
}

You may know it but IRIS is a database with the ability to execute code.

The code execution part is called an Application Server.

Today IRIS supports natively two languages: ObjectScript and Python.
Executing code is good, knowing how to organize it is better.

Organizing code is software architecture, not everyone has the desire or knowledge to create such a solution.
To do this, many programming languages offer what we call Frameworks.

Hi Developers,

Python has a large and powerful ecosystem that contains thousands of libraries and packages available, especially in data science.

Therefore, I wanted to have a first try in using a recent feature of IRIS called Embedded Python, to simply import a python library called datetime, generate data with a timestamp component and persist it in InterSystems IRIS for Health Data Platform. The same will work on IRIS Data Platform as well.

Hello,

I'm looking for a way to write a stored procedure or something to return a ResultSet with Embedded Python.

My goal is the following:

I have a Goal table with a Text field that is free text.

CREATETableId

I would like to create a procedure that returns all the entities (in the iKnow sense) in a new Entity column.

Python code, i would like to use :

'This is a test of the Python interface to the iKnow engine. another sentence to test this program with.'

Expected result :

How do I go about it ?

Hi Community,
In this article I will demonstrate the functionality of my app iris-energy-isodata .  
Application is accessing energy data (production, demand and supply)  from the major Independent System Operators (ISOs) in the United States to ensure sustainable consumption and production patterns (SDG's 12)

Application is using python library isodata , Production EXtension PEX  along with Embedded Python. 

Date and Time is an important factors in our life. Because all applications are engaging based on Date/Time. But our world is split into multiple time zones. if our product is launched in the world, to maintain the history of events we are definitely required to convert all times to our local time or UTC ( Coordinated Universal Time ). As I know, many known programming languages of C#, JavaScript, Java, etc., provided the library to convert the date and time. i.e with a time zone name we can be able to convert without knowing the UTC offset.

TZ database doesn't exist in InterSystems products.

In the previous articles, we learned the basics of using IMAP protocol to handle messages from mailboxes in an e-mail server. That was cool and interesting, but you could take advantage of implementations created by other ones, available in libraries ready to use.

One of the improvements to the IRIS data platform is the ability to write Python code alongside ObjectScript in the same IRIS process. This new feature is called Embedded Python. Embedded Python lets us bring to our ObjectScript code the power of the huge Python ecosystem’s libraries.
