anyway when I keep my native python scripts under "IRISinstalldirectory\mgr\python" and import my code as module and it's working because it's running inside the IRIS not using the python "driver" 

ClassMethod CallPyscripts()
{
    set ap = "mypyap"
    set pyImport = ##class(%SYS.Python).Import(ap)
    set builtin = $SYSTEM.Python.Builtins()
    do builtin.help(pyImport)
    write pyImport.irisversion,!
    write pyImport."Execute_Classmethod1"()
}

#__init__.py
import iris
from .irisembdpyth2024 import *

irisversion = iris.execute('return $zv')

# irisembdpyth2024.py file
import iris

def Execute_Classmethod1():
    print(iris.cls('MyLearn.EmbeddedPython').test1())

Hello @Guillaume Rongier

Thanks for the feedback! I go over your pretty useful article. I just write python code inside the ObjectScript itself by using language mode because of it's small code snippets. I actually facing some issues while writing IRIS in native python script.

From my pervious community question. First I install this intersystems_irispython-3.2.0-py3-none-any.whl in python and there is no cls, execute, routine, gref, ref or other IRIS script functions available.

As you recommend from the post. I install the official driver  https://github.com/intersystems-community/intersystems-irispython/releases/download/3.8.0/intersystems_iris-3.8.0-py3-none-any.whl file and I could use the IRIS functions for embedded python cls, execute, routine, gref, ref etc...

However, I got this ImportError: DLL load failed while importing pythonint: The specified module could not be found." error while executing the .py scripterror while executing my script

script is nothing but simple class method invocation.

import iris
def Execute_Classmethod():
    print(iris.cls('MyLearn.EmbeddedPython').test1())

Execute_Classmethod()

Hello @José Pereira 
I believe so. As per documentation this feature is not supported for some operating system.

Hello @Evgeny Shvarov 

I'm trying implement the embedded python syntax in native python. 

Thanks!. Definitely, However if I intstall https://github.com/intersystems-community/intersystems-irispython package I got some errors while ( seems some packages are overwritten) in my machine. So, I will try the both

Another option is to use the iris wrapper : https://pypi.org/project/iris-embedded-python-wrapper/

Hello @Guillaume Rongier

You Bet! I use web server port instead of super server port

Thanks for pointing!

And I'm trying to execute these lines from post  and git in to my .py source file. This functions are not available in iris library package.So, Is this code snippet is only applicable for embedded python. Please correct me If I'm doing wrong

If the below syntax works in python source file, What changed I need to do in my package.

    # switch namespace to the %SYS namespace
    iris.system.Process.SetNamespace("%SYS")

    # set credentials to not expire
    iris.cls('Security.Users').UnExpireUserPasswords("*")

    print(iris.cls('dc.python.ObjectScript').Test())

Thanks!

Hello @Raj Singh 

Certainly. There is no issue in the python installation in my different machine (windows).  I'm using my IRIS local instance to connect in both. No major difference except the port number and I'm using the super server port number in both cases. 

Thanks @Luis Angel Pérez Ramos 

It works. I downloaded and installed in python. However I got timeout error while trying to connect the IRIS in one machine  and it works in another machine. IDK pyodbc is required anyway it is also installed.

import iris

# Open a connection to the server
args = {'hostname':'127.0.0.1', 'port':52773,
    'namespace':'USER', 'username':'_SYSTEM', 'password':'SYS'
}

try:
    conn = iris.connect(**args)
    # Create an iris object
    irispy = iris.createIRIS(conn)
except Exception as e:
    # Handling the exception and printing the error
    print(f"An error occurred: {e}")

Hello @Tommy Heyding 

Thank you for pointing ToList in %SYS.Python It works for $LIST only not for the dynamicarray. Yes I believe the same convert the dynamic array to $LIST and send to the python. I grab the sample from doc

set clist = $lb(123, 456.789, "hello world")
set plist = ##class(%SYS.Python).ToList(clist)

Thanks Robert,

The validateIndices() and absolutely It's useful. For the first point. As far of my understanding both existing/newly created index both are set as "not selectable" at the time of building BUILD Index/%BuildIndices().  As per the documentation about the live system "not selectable" by default in BUILD INDEX. So, Does it applicable for programmatic %BuildIndices() as well?
