Trying Embedded Python

#Embedded Python #Python #InterSystems IRIS

This was my first attempt to use Embedded Python in IRIS
The Python code is adapted from solutions for Advent of Code 2020 contest.
Test data are all input to my personal challenge.

Make sure you have git and Docker desktop installed.

Installation

Clone/git pull this repo into any local directory

$ git clone https://github.com/isc-at/try_embedded_python

Open the terminal in this directory and run:

$ docker-compose build

this may take some time to complete

Run the IRIS container with this project:

$ docker-compose up -d

How to Test it

Using IRIS terminal:

$ docker-compose exec iris iris session iris "##class(rccpy.AoC20).Run()"

Welcome to embedded Python Demo
select day as described on https://adventofcode.com/

Hints

Directory .stream/ contains all my input files and some public test data.
If you want to use your personal input you should replace them as 1 file by day.
e.g. input01.txt, input02.txt,........ ,input25.txt exactly as downloaded from AOC2020.

%SYS.Python.html is a preliminary class docu to see available functions

run time: for most tests replies are pretty immediate.
But a few tests take a quite long time for calculations before showing a reaction.
Don't get nervous for day 11, 15!!, 17, 19, 22, 23.

Is it possible to have a version if this that doesn't require docker? I can't run docker on my laptop and am still getting my docker on Ubuntu on my Pi up and running.

Hello.

Talking about this example:

Class MyClass
{
 Parameter name = "Mario";

 Property nameProp As %String;

 ClassMethod SayHiPy() [Languague = Python] {
    this.nameProp = "Luigi"
    print("hi ")
    // call SayHiCOS() here
 }
 ClassMethod SayHiCOS() {
    s ..nameProp = "Luigi"
    w "Bye "_..#name
 }
}

I'd like to make the python method SayHiPy() equal to SayHiCOS() but:

1) when i call self.nameProp I get an Undefined on "self".

2) how can i get the class Parameter's value?

3) how can i call Objectscript methods in the same class from within the Python one, like calling SayHiCOS from SayHiPy?

Thank you
