Great article, can be useful ! Thanks.

Hi @ala zaalouni,

When you encounter this error :

The error appears: "An error has occurred: iris.cls: error finding class"

This usually mean that the Iop framework is not loaded into iris.

pip install iris-pex-embedded-python

you must init it to iris (install the associated classes to iris), for that you must do :

iop --init

or

from iop import Utils
Utils.setup()

please refer to the documentation :

For the more, make sure you are on the right namespace by specifying the var env : $IRISNAMESPACE

I would try something like this :

ClassMethod "test_dict"()
{
    set pythonObj = ##class(%SYS.Python).Bytes("toto")

    set dict = ##class(%SYS.Python).Builtins().dict()
    do dict."__setitem__"("my_bytes", pythonObj)

    w !, dict."__getitem__"("my_bytes")
}
